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. :

A: Hello – We recommend using a 50:1 fuel mixture for optimal performance with this model. Please see the operators manual for more details.
Most modern chainsaws, string trimmers, leaf blowers and other small-engine two-stroke equipment recommend a 50:1 oil mix ratio, but some recommend 40:1 and older two-stroke equipment might even call for 32:1.
Use a 40:1 two-cycle oil mix ratio. One gallon of gasoline combined with 3.2 oz of two-cycle engine oil.
For a 50:1 ratio of gas to oil, use 2.6 fluid ounces of oil per gallon of gas.
Common gasoline and oil mix ratios are 50:1 and 40:1. Meaning there is 50/40 parts gasoline to one part oil when mixed. The lower the mix ratio number the more oil per volume in the gasoline. To mix properly add oil to your gas can, then add fresh gasoline from the pump.
Most STIHL gasoline-powered equipment runs on a 50:1 mixture of gasoline and 2-cycle engine oil. Knowing the proper way to mix your fuel is the first step in keeping it running strong and long.
It may be reminded that the GOR (gas/oil ratio) is defined by the relation GOR=V g/V o, where V g and V o are respectively the volumes of gas and of oil produced at the surface under standard conditions.
You`ll need STIHL 2-Stroke oil, an empty and clean fuel can & fresh unleaded fuel from a reputable petrol station. Mix at 50:1 (20mls oil per 1 litre fuel) when you`re using STIHL 2-Stroke oil.
For a mixing ratio of 1 : 50 you need 5 litres of high-octane gas and 0.10 litres (100 ml) of STIHL two-stroke oil.
Running a 2-cycle with the wrong fuel to oil mixture can cause severe damage to your engine. Running the machine without any oil mixed in the fuel can cause severe damage to your equipment within just minutes. This damage is generally very costly to repair and is usually irreparable.
Modern gasoline chainsaws run at 50:1 mixture, 50 parts gasoline to 1 part oil. Older chainsaws can require 16:1 mixtures or 32:1 (most common). Two-stroke engines are much more efficient now, as well as having cleaner combustion. At most automotive stores, pre-mix fuel can be bought in 50:1 and 40:1 mixtures.
What is the ratio for 2-stroke fuel mix? Most modern petrol garden machinery requires a 50:1 ratio mix of petrol to oil. This means for every 1 litre of petrol you must mix 20ml of oil.
Choosing the right unleaded fuel & right two-stroke oil

If not using a premixed fuel and oil blend, you should always use unleaded ethanol-free gas for your outdoor power equipment.

If you`re using a different brand of 2-Stroke oil, you`ll need to mix at 25:1 (40mls oil per 1 litre fuel). Petrol has limited shelf life (as low as 30 days), so always mix with fresh regular unleaded purchased from a reputable large volume fuel supplier.
A: 25 :1 ratio is 25 fluid ounces of gas per 1 fluid ounce of oil.
100:1 – Mix 50ml of oil per 5ltrs of fuel.

Recommended by Yamaha and Suzuki for most of their small two stroke engines up to about 30hp, this ratio requires the least amount of TCW3 two stroke oil. The result of using this ratio (less oil) is reduced spark plug fouling and less smoke.

Step 1: You`ll need STIHL 2-Stroke oil, an empty and clean fuel can and fresh unleaded fuel from a reputable petrol station. Step 2: Mix at 50:1 (20mls oil per 1L fuel) when you`re using STIHL 2-Stroke oil. If you`re mixing a larger quantity, check out our useful mixing chart.
A carbureted two-stroke engine can emit up to 25-30 percent of its fuel unburned into the water or atmosphere, which is why high-emission engines are prohibited on some lakes.
What happens if the mixing ratios in a 2 stroke engine are incorrect? If you put too much oil, it can generate additional carbon build-up, making it difficult to start the engine, blow excessive smoke which is particularly bad for the environment and may (with time) cause the engine to stop operating correctly.
Gasoline that is 89 octane or higher is specifically recommended in engines that are two stroke and air cooled. Gasoline may contain a MAXIMUM of 10% Ethanol. Two stroke air cooled engines are approved to use a 87 octane rated clean gasoline in emergency situations.
40 to 1 ratio

This equals 25mls of two stroke oil to 1 litre of petrol.

Can I mix premium and unleaded gas? Yes, drivers can mix the two types of fuel. The combined gas types will result in an octane level somewhere in the middle — something the vehicle “will survive,” according to The Drive.
Two-cycle engines use a mixture of oil & gasoline in a single fuel tank. Four-cycle engines do not require mixing of oil & gasoline and have separate gasoline and oil tanks. Here are some easy ways to tell if your engine is two-cycle or four-cycle: Look at the fuel cap.
But running a two-cycle engine with too little oil can actually destroy the unit. Oil helps cool the piston and cylinder by keeping them evenly lubricated. Without lubrication, the metals can melt and potentially grate against each other, transferring metal to and from one another and permanently distorting them.

I have the Intex Sand/Pump pool filter Model SF 20110. It’s been running real great for the last 4 months. However recently it has been tripping the internal overloads and I have found the pump motor to be very hot when I put my hand against it. I have tried several different solutions, such as a level ground platform that was clear of any obstructions, made sure that the motor vents under the motor was clear of anything that would prevent air flow. I used a non electrical type of lubricate on the impeller. When I would turn on the pump the rotor would not turn but only would hum very loudly and then slowly begin to turn. I also noticed that the motor’s rotor shaft would not turn to freely due the tightness around the rotor’s shaft. After using the lubricate the shaft would turn a little easier. I used an amp meter on the incoming voltage line and the motor would run at 4.5 amp. And yet it still overheated and tripped the motor overloads. I can only think that the motor is still not getting enough ventilation. I have check and cleared all the incoming lines and found nothing block the pumps input or output lines. Any suggestion?
ANSWER : I just looking into this issue my self. The pump cools itself by a internal fan, which is run by the motor. Well I took the housing cover off to find out all the fan blades have broken off and were setting in the base of the pump. Once you remove the fan blades from covering the air intake, it might be fine. I will find out my self once summer gets here.

I bought the Knoxx adjustable stock for my mossberg 500. The forend that comes with it is realy nice and Ide like to use it, but the end nut will not reach the threads. Do i need to buy a new adapter nut that is longer to secure my forend ? I saw one for sale by houge but wasnt sure if that would work on the knoxx forend ?? I realy like the forend sent by knoxx, would be a shame not to use it. What a waste to give that nice piece away and not give the adapter to use it ?? Thanks Noel
ANSWER : That forearm is designed for the 7 5/8″ slide action tube. I’m guessing yours is the 6 1/2″ slide action tube. Take the forearm off your tube and measure it with a ruler. From the very back edge of the action bar collar….that round part the bars are pinned to….all the way to the front edge of the threads. If yours is a 6 1/2″, the Hogue adapter won’t work. You’ll need to buy a new slide action tube. That Hogue adapter is meant to let you use the Hogue rubber coated forearm on your standard sized tube….the Hogue rubber forearm is a hair longer than the standard tube. It won’t give you the length to make up the entire shorter tube length. If you’re handy with a dremel, you could go adapter plus a bit of careful cutting but I won’t suggest you do it if you aren’t certain of your skills.

Hiya I have a fujifilm e-900 I have used the camera less than 20 times. The last time I used it I had no problems at all. I had left it sitting in it’s case for 6 months. Now when I try and us it I get the hand with lightning bolt on the lcd. Which I assume means the battery encasement is open. It isn’t open. The camera turns on no problem then when I try and use any function it shuts down. How do I fix this?
ANSWER : The hand with the lightning bolt icon usually means the camera is telling you that there is not enough light and you need to pop the flash up before you take a picture.
If you haven’t used the camera for a while have you tried fresh batteries or charged the 2 re chargeable AA’s that came with the camera?

I have purchased three 750-watt power inverters in the last three weeks. They have all failed to work on the second or third use. The first two were the same brand. I replaced an old one that ran for several years. I am using it to run a 4.7 amp 120-volt vacuum cleaner motor that pumps up my air dock. I have it connected directly with marine cable to one of the boat batteries. The battery outputs about 12.8 volts DC. The fuses don?t blow, just No Output. I am using a three-wire 120-volt extension cord and am, wired neutral, hot and ground to the AC motor vial an on/off switch. The motor works fine when I run house power with an extension cord from the dock next to me. Could I be, just unlucky with new inverters and need to buy a forth one?
ANSWER : The problem may be that the inverter is undersized for the load. Is the 4.7 Amp rating the motor peak draw or the nominal one. What I mean is that it takes many times more power to start start the motor than when the motor is running. Typically it is 3 to 7 times more amps to start the motor than when it is running. It could be that starting the vacumm cleaner is stressing the inverter and it is causing it to fail prematurely. If you can find out the locked rotor current draw of the motor, the that would be the mininum size of the inverter.

Also, the type of inverter will make a difference on how the motor operates. A modified sine wave will make the motor run hotter than a pure sine wave inverter. Hope this helps.

We have had this treadmill for a number of years and had not been using it much in past year. We now wish to begin using it again but am wondering if I should oil it. Need to know type of oil and locations on treadmill where this should be done
ANSWER : Hi Bernard
well this will depend on what model it is, is it electric? or is it just a friction type? if it is a friction type, a little wd40 just around the bearings should loosen it up a bit try not to get any on the underside of the belt as this could make it slip on the rollers, but if it is electrical, there is no need to lube it at all as these have heavy duty sealed bearings in which are lubricated inside, so really there isn’t much to really do to them or it should i say, hope this helps please vote and rate tanks

XD Picture Card
ANSWER : It does say 128 in the manual, but I would assume that is because that was the largest available at the time of print.
As long as the card is XD, the storage capacity should not matter.
