Log Splitter: Engine won’t start

A dirty carburetor, bad gasoline, failed spark plug or broken recoil starter can prevent the log splitter engine from starting.

Stale gas won’t start the engine. If you left gas in the fuel 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.

Bad gasoline can clog the carburetor, so clean and rebuild the carburetor if the engine doesn’t start after replacing the gas in the fuel tank. Replace the carburetor if it’s too clogged to clean.

A dirty spark plug won’t ignite the fuel to start the engine. Complete a full tune-up that includes replacing the spark plug, air filter and oil.

If the recoil starter won’t spin the engine when you pull the starter rope, then you’ll likely need to replace the recoil starter.

These repairs may help solve your Log Splitter problem:

Replace the log splitter carburetor

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.

Replace the log splitter recoil starter

Recoil starter

The log splitter's recoil starter engages and starts the engine when the starter rope is pulled. If the pull rope doesn't retract, it's likely that the spring inside the recoil starter is broken. The recoil starter can also fail to engage the engine when the rope is pulled, and the engine won’t start. Replace the recoil starter if the spring breaks or if the recoil starter doesn't engage the log splitter engine.

Rebuild the log splitter carburetor

Carburetor rebuild kit

Rebuild kits are available for most log splitter carburetors. The carburetor rebuild kit contains essential components such as jets, pins, seals and gaskets for overhauling the log splitter carburetor. You can sometimes fix a fuel supply problem by disassembling, cleaning and rebuilding the carburetor.

Tune up the log splitter engine

Air filter

A tune-up restores the log splitter's engine to its peak operating condition. A tune-up includes changing the oil, cleaning the engine, replacing the air filter, checking the ignition system, inspecting the carburetor, adjusting the throttle and choke controls, and adjusting and lubricating all moving parts.
