Tiller: Engine leaking oil or gas

Engine problems can cause oil or gas leaks. If you notice stains on the pavement or garage floor, investigate the source of the leaking fluid. For an oil stain, check the head gasket, sump gasket and the oil drain plug. A loose or cracked fuel line can make the tiller engine leak gas. Move the tiller to a well-ventilated area and exercise proper safety precautions if you discover a gas leak. The repairs listed below could help you resolve a problem with gas or oil leaking from the tiller engine.

These repairs may help solve your Tiller problem:

Replace the tiller carburetor

Carburetor

Over time, varnish from stale gasoline builds up in the carburetor, decreasing the amount of air/fuel mixture reaching the engine. Replace the 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.

Clean and rebuild the tiller carburetor

Carburetor rebuild kit

Rebuild kits are available for most carburetors. The kit contains the essential components such as jets, pins, seals and gaskets to overhaul the carburetor. You can sometimes fix a fuel supply problem by disassembling and cleaning a carburetor. Use the rebuild kit to rebuild the carburetor after cleaning it.
