Fuel is a common culprit behind engine problems. “Start by checking the fuel tank. If it's empty or low on fuel, add more fuel into the tank and try again,” says Melody Estes, Landscape Design Gardening Supervisor and a consultant at The Project Girl (opens in new tab).
Has your chainsaw been gathering dust? If your chainsaw is unused for over 30 days, the fuel tends to become stale and sticky, which affects performance. If you suspect this is the case, drain the old fuel and replace it. Sticky fuel can clog the fuel filter and the carburetor. Clean both and check whether that resolves the issue.
“If that doesn't work, check the spark plug. It should be connected securely to the engine and in good condition—if not, remove it and clean it with a wire brush before replacing it,” advises Melody.
If the engine stops when you hit the throttle, take it as a clue that the problem is the spark arrester. Clean it with a soft wire brush.
The weather is another factor. Cold conditions can affect your chainsaw performance. Try pulling out the choke and see if that helps.
If you smell fuel, it’s a tell-tale sign that your chainsaw is flooded. Follow the steps in our guide to how to unflood your chainsaw.
