Fuel in the exhaust

Gabor Levente /

Hello everyone. When I crank the engine over to start it no fuel is getting to the spark plug. Instead it goes out on the exhaust pipe. The cylinder piston and rings are new. Also the gaskets are new. Compression is good. Any idea if this is normal or can anybody tell me what the problem could be?

You left the petcock open for a period of time and the cases flooded?

No. I always close it. When i open the petcock i see the fuel going trough the fuel line

Re: Fuel in the exhaust

If fuel is always flowing when the petcock's on your float is either stuck or nonexistent and your motor is flooding.

2nd for float needle leaking - clean carb, replace float needle

Re: Fuel in the exhaust

You might have to replace the needle as michael but first look for trash keeping it from closing off

Found it. As I changed the piston and cylinder they were a bit different from the original and the piston didnt went out enough to open the transfer ports.
