The bowl on this 6.5 hp Honda clone is leaking gas. This is one of the blue $90 Harbor Freight 6.5 OHV engines. It has never given me any trouble as a transplant on this HS-520 snowblower. Last spring I drained the bowl at the end of the season. I was surprised when I filled the tank with gas today and found it dripping out (pretty fast) around the bowl o-ring gasket/seal. At first I thought I might need a new o-ring, but shouldn't the float and needle be shutting of the flow of gas the bowl before it starts pouring out? Do these clones take normal honda carb parts? Any suggestions on where I should start? The engine still starts up and runs perfectly, it just leaks gas bad. I cannot find a part number for a replaceable seat.

Borat - good point about the leak being caused by vibration !  I hadn't factored that into my thought process.  I knew I could count on you.

Running great now. I got the carb bowl off and it was really bad. Filled with grit and pieces of corrosion. I cleaned it out and then ran a ball of sandpaper round and round through the bowl until it shined. With the float and needle removed I took a Q-tip and some polishing compound and polishes the metal seat where the rubber needle makes contact. The O-ring on the bowl did not look great but it was re-used and does not seem to be leaking. Rebuild parts kit is Primeline number 7-070024, whole replacement carburetor from them-Primeline part number 7-01224.

Fantastic !

Keep an eye on the bowl gasket for any leaks...just in case !

Nice!!!
