I have tried everything but can’t get my chainsaw to run properly and looking for help. “I have adjusted the carb and I can start it with about 10 pulls and it idles fine. I pull the trigger and it seems fine. However, I get halfway through a 15” log and it dies. I can restart the saw with 1 pull no choke and it idles fine but when I start in the log again it immediately dies. This goes on for the rest of the day 1 pull starts and give it gas and it dies at high speed. It seems it will idle forever fine but it just will not cut anymore. I have messed around with the carb settings for hours without luck. The new fuel line was slightly thinner than what was on it but I thought that the old line may have swelled from the gas in the fuel line over the years.
4.) Now, back to the “Not good” part concerning the single ring… With that single ring, all the wear from running is heaped on that single ring. 010″ of ring end gap, but anything in the.020″ and up for end ring gap will cause marked loss of compression and will result in the saw running poorly, and potentially dying when hot. “If the compression changes dramatically, I’ll have to open the powerhead up and check the ring end gap. If the ring end gap is above.015” or so when cold, and the cylinder wall is not scored then most likely just changing the ring should breathe a little more life into the saw.
chainsaw dies when hot Related Question:
Why does my chainsaw keep dying?
A clogged carburetor is often caused by leaving fuel in the chainsaw for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the chainsaw engine to stall.
How do you stop a chainsaw from overheating?
To prevent chainsaws from overheating they must be cleaned regularly. The cylinder and starter both contain air intake areas that pull cool outside air into the engine when it’s running. If dust, wood chips or other material blocks these systems, the engine will start to overheat.
What causes a chainsaw to vapor lock?
Vapor lock occurs when the fuel (usually gasoline) within the fuel delivery system overheats and vaporizes too rapidly. The resulting excess gas bubbles accumulate to the point of actually blocking normal fuel delivery.
Why does my chainsaw chain get hot?
Overheating occurs when there is a mismatch between the chain drive and the groove blade. Your chainsaw must have a perfectly matched chain and blade because they are aligned on each other. A size mismatch will cause overheating and even smoking of the blade.
How hot should a chainsaw get?
How Hot Does A Chainsaw Crankcase Get? The oil conductor does not provide sufficient heat protection to keep the engine cooler; instead, the oil is more efficient at drawing heat to it instead. At temperatures over 220 Fahrenheit and occasionally as high as 220F, it often stratifies on top of an oil pan.
How long can you use a chainsaw for?
What is the runtime of a Chainsaw? Depending on the type and usage, you can expect a gas Chainsaw to run between 15 and 40 min before you have to fill it up again. Most battery-powered chainsaws have a run time of up to 2 hours, but there are high-capacity power packs that will last much longer.
Why does my Stihl chainsaw bog down?
Stihl carburetors have three adjustment screws. One controls the fuel mixture when the engine is idling, one controls it when the engine is operating at low speed and one is for high-speed fuel control. When the saw bogs down during cutting, it’s usually the high-speed screw you need to adjust.
How do I know if my chainsaw spark plug is bad?
If it’s not producing any sparks at all, your chainsaw needs a new plug. If there are only a few sparks coming out of one side of the electrodes but none on the other side, it’s not bad enough for you to worry about, but it will affect your performance.
Why does my chainsaw bog down when I give it gas?
If your chainsaw is bogging down when you give it throttle, this is often a sign of improper gas-to-oil ratio. If there is too much gasoline in relation to the amount of oil used, this is known as a “rich mixture” and can cause the chainsaw to run poorly.
How long does it take a chainsaw to cool down?
Do Refuel Your Chainsaw Safely One tip for how to safely use a chainsaw is to never refuel when the chainsaw is still hot. The heat from the engine could ignite the fuel. Instead of taking the risk, let the chainsaw cool down for 10-15 minutes before adding fuel.
How do I adjust my chainsaw for cold weather?
Give the saw a fresh spark plug, clean the air filter, and if the saw has a shutter for the carburetor, switch it to its winter setting. Next, drain the bar and chain oil and switch over to a thinner, winter-grade lubricant. You may be able to thin your bar and chain oil with a little kerosene or diesel fuel.
Should you run a chainsaw at full throttle?
Engine Protection Generally, two-stroke chainsaw engines are built to conveniently run at full throttle without an engine breakdown. Therefore, running at any throttle speed below the full throttle is not advised.
Is it worth sharpening a chainsaw chain?
Sharpening your chainsaw chain is definitely worth it as a sharp chainsaw chain is easier to work with. It takes less effort to cut through wood and your chain will make cleaner cuts with sharp blades. A chainsaw chain can be sharpened multiple times without much of a cost.
