many possible causes but without a repair manual I don’t know where to start checking for the problem.
Is there a common spark problem with these ATV’s?
Thank you for your help.

How to Identify and Resolve Common Issues ?
We offer a diverse range of insights on identifying and resolving common problems in sports. Our sources encompass academic articles, blog posts, and personal essays shared by seasoned athletes. :
What is this? The most common reason an ATV is getting no spark is a bad spark plug, either the wrong plug all together or just not gapped correctly. Or the spark plug just went bad, that happens quite often and it`s normal.
If no spark appears, check for broken wires, shorts, grounds or a defective stop switch. Once you have confirmed that the stop switch is working, reconnect the spark plug lead.
The engine is not getting enough spark
If the engine turns over but doesn`t stark, it may be getting a weak or insufficient spark. An insufficient spark will be unable to ignite the fuel and get the engine running. There is a quick and easy way to determine if that is the case.
Place the black multimeter lead on one of the terminals on the CDI box. Touch the red multimeter lead to each of the other terminals on the CDI box, one at a time. If the multimeter reading changes when you touch the red lead to different terminals, then the CDI box is functioning properly.
If the ignition coil does not have spark, it`s time to check its wires. Use a test light to check the continuity on the signal wire and power wire on the ignition coil. If both wires are functional but the coil fails to produce spark, the ignition coil or the ignition control module is bad.
The most common reason cars don`t start is a dead or faulty battery. Even though most cars run on gasoline, they all require electrical power to function. The starter that cranks your engine to start requires an electrical signal to fire. If something`s wrong with your battery, your car engine won`t turn over.
Misfire – A cylinder misfire occurs when the spark plug can`t ignite the air-fuel mixture. This can occur because of worn spark plugs, contamination, cracked spark plug wires, or other problems.
If the wheels aren`t turning, use a jack to lift the ATV off the ground. Check each tire to see if there`s any play by wiggling them back and forth. If there is excessive play, your issue likely stems from worn wheel bearings, and you`ll need to replace them. Take off the tire and try spinning the wheel by hand.

Incorrect timing is the most overlooked and misdiagnosed cause of a no-start. Perhaps you automatically think of ignition timing as the position of the crankshaft when the No. 1 plug fires. While this is important, it isn`t the only timing condition that can influence a no-start.
A spark plug is an electrical device used in an internal combustion engine to produce a spark which ignites the air-fuel mixture in the combustion chamber.
The starter will not have any impact on the engine`s ability to produce spark. There are a number of issues that may cause an ignition system to not produce spark. A bad crankshaft position (CKP) sensor (on engines that do not have a distributor), or broken, loose or corroded wires from the sensor to the PCM.
The crankshaft position sensor monitors as a multifunctional sensor used to set ignition timing, detect engine RPM and relative engine speed.
If the ignition relay shorts, burns out, or otherwise fails while the engine is operating it will cut off power to the fuel pump and ignition system. This will cause the vehicle to immediately stall due to fuel and spark being cut off.
Failing spark plugs can cause the car engine to misfire and thus affect its performance. A single spark plug that fails to ignite the fuel-air mixture can cause a halt in the running of the engine. It can result in incomplete combustion and damage to the catalytic converter of the car.
Spark plugs may become less effective at doing their job due to time, wear, or other electrical/ignition system issues. They may become “fouled” over time due to combustion, contamination, or overheating, losing their ability to spark the air-fuel mixture and dissipate heat away from the combustion chamber.
If the battery level is too low, or you`re riding with an old battery, you`ll likely have a problem starting up your ATV or UTV. You can check the battery`s level using a voltmeter. Just be sure to follow the battery`s recommended charging rate to avoid overcharging.
If your ATV has spark and fuel but will not start, it could be something as simple as the petcock valve in the off position. Double-check the petcock valve as soon as you suspect engine issues. If your ATV`s petcock valve is not in the ON or RUN position, put it there. Try starting the engine again.
The cleaner your air filter, the more horsepower your off-roader is able to produce. Some quad racers will even upgrade their air filters to high-flow filters that boost performance.
The only way to really know if your engine is locked up is to take off the pull start on the rear, take the spark plugs out, and try to move the crankshaft with a socket on the crank bolt. If you`re able to get something to move, you`re in the clear. If nothing happens, then your engine is likely locked up.
CDI has another full form and its – Capacitor Discharge Ignition. CDI (Capacitor Discharge Ignition) is a type of electronic ignition system used in automotive, like motorcycles, outboard motors, chainsaws, lawn mowers, turbine-powered aircraft, small engines, and some cars.
Sometimes called the “HT coil”, for short, the High Tension coil is integrated into the ignition control unit. When the HT coil needs the spark to ignite the fuel, it gets the power from the capacitor inside the CDI unit.
So, if your mechanic has a “better” CDI, it either doesn`t actively limit the max. RPM, or it has a better timing at higher RPM, allowing more power output and hence top speed.
Spark issues are the most common symptoms of failing stators, known as “Misfiring.” If you haven`t already known, stators are directly responsible for producing the required spark for your spark plug. Once they malfunction, the motorbike will receive insufficient – or worse, zero – sparks.

Spark plug wire boot grounding out on coil, 96 outback 2.5 automatic, just put new spark plug wires, new spark plugs, and new coil on. ran great for two weeks, now spark is jumping out of boot at coil on one wire, put old coil back on and still does it in the same spot. replaced wires again, and still does it in the same spot. seems to do it only under a load. Is my new spark plug on that cylinder bad? Does the coil need some insulation under it? It is the coil that sits right on top of the motor. Any ideas? thanks.
ANSWER : Sparks are high voltage, and will always follow the path of least resistance. If you can visibly see a spark (whether in a lighted area, or in the dark), that means either that a plug wire (or coil wire) is open (non conductive), or your have a carbon track on the surface where the spark can be seen, but most likely you have BOTH problems!
If you have an ohmmeter, check the resistance of each wire involved, particularly spark plug wires … which means you must be able to connect to both ends of each wire at the same, and hopefully, FLEX those wires, to be sure they don’t have a break inside that is intermittent (comes and goes)!

HI!
I continually get code 90 (low/NO flow) from my 8111. I have disassembled, cleaned EVERYTHING, including the inlet port AT the pump (remind everybody to check this as stuff gets past the filter basket and will plug the pump inlet).
I continually get code 90 (low/NO flow) from my 8111. I have disassembled, cleaned EVERYTHING, including the inlet port AT the pump (remind everybody to check this as stuff gets past the filter basket and will plug the pump inlet).
There is No air in the system and I get superb pressure at the outlet, yet I still get code 90. I again removed the flow sensor and put my ohm meter across the flow sensor terminals and activated the flapper and measured an open circuit. I used a heavier magnet to see if I could get make the internals of the sensor move to get an ohm reading, but I get nothing but an open circuit, ie: no measured resistance.
Can I simply bypass the defective flow sensor to trick the 8111 to think it has full flow without damaging the ‘brain’ of the system.?
Intex corp is useless at these questions. They have been out of stock on this sensor for months and are telling me “two weeks” for two months and now it’s “end of August” which I do not believe. Meanwhile I am making no chlorine while the 90 code is showing.
I love the 8111, this is the first problem I’ve had with it, and I’m frustrated that I can not get such an important part from them.
Thanks for listening!

I have a Kohler Condidant 5 Generator that will run as long as you hold the start button in. It dies when you let off. I have a harness for the remote switch but no switch – It also will start the generator when you cross the red and black wire and run as long as you hold them together. There are 3 wires to the main switch and 5 to the remote switch. Does the starter stay engaged the whole time you hold the start switch or does the computer release the starter once it is running? The Generator is producing electricity because I tested it while holding the start button. Some where is a wire that shold tell it to keep running. I have read online many descriptions of the same problem, most are told the board is bad so they replace it and still have the problem. Have not found a solution. Talked to a marine machanic today and he said he fixed his friends generator doing the same thing by running a bypass wire but he couldnt remember exactly what he did it was a long time ago. Can anyone help me. Thank you
ANSWER : The problem is either the ballast resistor or the starter bypass relay. The bypass relay should be part of the starter solenoid. I’m afraid I can’t tell you exactly where the ballast resistor is located. It should be a physically fairly large resistor made of ceramic. It should be retangular roughly 1.5″-3″ long and 3/8″-1/2″ accross with a wire on each end. It could also be a coil of wire mounted on a phenolic board.

Turned poulan pro 42 inch 18.5 HP Briggs and Stratton mower off after 1hr of use to move a board I was about to mow over. Tried to restart it but it just backfires. Removed spark plug and it looked fouled. Cleaned it up but when looking at spark it is orange in color. Bought new spark plug and now get white spark. Installed new spark plug and it still backfires. Plug is wet with gas. Any suggestions?
ANSWER : Check the valve clearances and especially the inlet valve to make sure that it is not riding (staying slightly open) B&S are notorious for valve problems as most of their motors do not have a valve adjustment on them, the valves stems have to be filed/ground down to get a clearance. Somewhere between 0.010 to 0.015″ is near enough for the inlets and about 0.005″ more for the exhaust. It is not critical.

I,ve got a Kawasaki super sport xi (jh 750-b) it hasnt been started ffor a couple of years so its my job to get it going so i’ve cleaned out the water jet (cause it had some big stones in) got some new spark plugs and tried kicking it over, there NO SPARK now. And also i could turn the propeller and it wasnt turning the engine, is that true. My friend said it had sucked up a stone and snapped somekind of bolt is this true. If its the coil packed buggered thats why there no spark where can i get another…. Many thanks carlie
ANSWER : Two problems if there is no spark it could be several things, the prop not spining is normal if you sucked up rocks, it’s design to do that to save the motor. It’s a rubber spacer. I’m parting out my 750 xi ss. Let me know if you need parts [email protected]

I have a 2004 60 hp yamaha 2 stroke outboard engine that doesn’t start or run well. Once warm and in the water it will idle in nuetral and also in gear. It accelerates in neutral but will die or lack power if I increase throttle while in gear. Engine will somtimes get to top speed but often while running at top speed engine will start to slow rapidly. Engine has full range of operationout when out of the water where there is no load on engine but is still difficult to cold start. Before these recent problems the engine sat up for several months and I had to change the impeller and spark plugs. Spark plugs fire, cylinders have proper pressure of 100, 100, and 110. I cleaned some fuel lines and filters and got new gas.
ANSWER : Every sympton you are describing here can be attributed to fuel starvation due to blocked jets and or water in carbs, when your engine dies does it die with dry plugs, or wet oily ones?

I bought a new mossberg 590 a1 shot gun a month ago, I love the gun but its having a couple of problems, the first problem is that when shooting every once in a while i get sprayed in the face with exuast from shooting through the safety very scary! any ideas whats causing this? how to fix it? second is that some times the fireing pin sticks and the gun will not discharge a round? the third problem is that i have had feeding issues with gun where it will not realice a gound from the tube, ive taken a tip of a knife to the stuck round in the tube and it prys out with little effort, these problems dont happen every time i go shooting, just every once in a while, but they a happening more and more, im conserned cause the gun is brand new, and i wanna be safe while shooting, can you guys help me? any ideas/solutions? please help!!!!!!!
ANSWER : Personally, with that many problems, I’d call Mossberg and get a return authorization. None of these things should be happening, especially with a new gun.
