If it has a carb and is a two stroke check the gap on your spark plug and make sure your main jet is adjusted right. but it sounds like your sled is running to rich. look at the end of your spark plug, if it is black you are running to rick but if it is kind of a white color it is to lean. it should be pretty close to tan.
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. :
Wet Fouling, 2-Stroke
The appearance will be the same as a wet-fouled 4-stroke plug. Causes include the wrong plug (too cold), excessive idling, improper fuel:oil mix ratio or carburetor adjustment set too rich.
Found in many passenger vehicles, hot spark plugs have more insulation to transfer the heat slowly, which keeps the temperature high enough to burn off carbon deposits and avoid premature fouling. This helps allow for more time between spark plug changes.
A sled can flood if the engine is over-primed or over-choked. One way to correct this problem is to simply give it time. Let any extra fuel evaporate for about 20 minutes before restarting. You can also attempt to dry the spark plugs on your own if you don`t want to wait.
Causes of a carbon-fouled spark plug include a dirty air filter, excessive driving at low speeds, too rich of a fuel/air mixture, dirty fuel injectors or idling your vehicle for too long.
Since platinum is harder, it holds its sharp edge much longer than a conventional spark plug, up to 100,000 miles. Longevity is a key advantage of platinum spark plugs. Another advantage of platinum spark plugs is that they run a little hotter, which burns deposits off the spark plug better and helps prevent fouling.
Yes, you can clean an old, fouled plug. However, it`s best to opt for a spark plug replacement in most cases. That`s because an old spark plug won`t perform as well as a new spark plug. After all, electricity discharges best from sharp edges that only a new plug can have.
Champion plugs are hotter the higher the number, colder the lower the number. Starting with part # RCJ7Y (heat range 7), a colder plug would be # RCJ6Y (heat range 6), a hotter plug would be # RCJ8Y (heat range 8).
The heat range of a spark plug is the range in which the plug works well thermally. The heat rating of each NGK spark plug is indicated by a number; lower numbers indicate a hotter type, higher numbers indicate a colder type.
When there isn`t enough snow, this can also cause overheating. Such overheating usually occurs at the beginning of the snow season. Other common causes of overheating include faulty wiring or a clogged exhaust pipe, all of which can cause problems for a sled.
Many times, darting is caused by having too much ski pressure. Because there is so much pressure being forced onto the skis, the runners will bite and “dart” at any random time. You can adjust your snowmobile`s suspension so that there is not as much ski pressure.
Overflowing engine oil can also lead to bent engine rods and collapsed valve pipes. Spark plug fouling – Excess oil can find its way into spark plugs, which will then need to be replaced.
Black, dry soot on the electrodes and insulator tip indicates a carbon-fouled plug. This can be caused by a dirty air filter, excessive driving at low speeds, too rich of a fuel/air mixture or idling your vehicle for too long.
Indeed, iridium spark plugs are generally considered more durable than other kinds of spark plugs (like platinum ones). Nonetheless, they`re not invincible and can still foul and corrode. Oil, fuel, or carbon can foul iridium spark plugs just like platinum.
In general, a light tan/gray color tells you that the spark plug is operating at optimum temperature and that the engine is in good condition.
What causes tire blowouts? According to Tire Rack, many blowouts are caused by underinflated tires. When the air pressure in a tire is too low, the tire may flex beyond its limits, overheats and cause the rubber to lose its bond to the tire`s internal fabric and steel cord reinforcement.
Gathering your hair into a loose, messy bun before bed is the best way to make your blowout last overnight. Find a hair tie that won`t create a crease—Scrunchies work well, as do claw-style hair clips. You can also wrap your hair in a silk turban to make your blowout last longer.
If the PCV valve is stuck open, the excess vapors and oil droplets can quickly foul the spark plugs.
Is it safe to spray WD-40 in a spark plug hole? Yes. WD40 is a water displacer, not a very good lubricant, and a bit of a solvent. If you need to spray anything int he cyclinder, it should be a penetrant like PB Blaster or even some oil.
Clean the spark plug thoroughly to avoid problems later. Remember, if a plug is fouling, its usually a result of engine side factors or incorrect heat range selection. If, after cleaning, a plug shows unusual signs of wear or doesn`t come clean, its time to replace it.
A hotter plug does what is says, it runs hotter. This will not give any more power and neither will a too cold plug. Because the spark plug resides in the combustion chamber, it`s influenced by what happens there.
The copper core does transfer a significant amount of heat. Reeves emphasized that the heat range rating of a copper-core spark plug and an iridium plug will be the same and that it is the tip (overall) length of the center ceramic that determines any plug`s actual heat range.
Iridium Spark Plugs – Service Life
Denso Iridium spark plugs use a much thinner electrode than even the NGK. Given how long the NGK electrodes last you could argue the NGK are over engineered and reducing their diameter would have no effect on their service life.
Is that hot? The heat range of a spark plug is indicated by the number in the plug`s identification sequence. On NGK spark plugs, the lower the number the hotter the plug (higher numbers are colder). Thus, your NGK BR9ES is colder than a BR8ES.
