Log Splitter: Why does my log splitter's engine run rough or misfire?
When your log splitter engine isn't running smoothly, cleaning or replacing the carburetor, tuning up the engine or replacing bad gas may fix the problem.
If you left gas in the tank for more than 6 months without adding fuel stabilizer, drain the tank and fill it with fresh gas. Add fuel stabilizer to gas to keep it fresh.
Stale fuel can clog the carburetor, so clean and rebuild the carburetor if the engine continues to run rough or misfire after replacing the gas in the fuel tank. Replace the carburetor if it's too clogged to clean.
Tune up the log splitter engine by replacing the spark plug and oil. A dirty spark plug won't ignite the fuel properly. Old oil won't lubricate engine parts well so the engine idles roughly because the piston or pistons won't move smoothly through the cylinder.

Replace the log splitter carburetor
The log splitter's carburetor mixes air with fuel in the proper proportion to produce a combustible gas. That gas/air mixture is pulled into the cylinder, where the piston compresses it and the spark plug ignites it. Over time, varnish from stale gasoline builds up in the carburetor, decreasing the amount of air/fuel mixture reaching the engine. Replace the log splitter carburetor if it's severely clogged with varnish or if the orifices are clogged with debris and can't be cleared using carburetor cleaner and compressed air.
