Hi All,

I have a Honda GX31 31cc four stroke ingnition engine that I'm having problems with and hope someone out there might have a clue what's going on. The GX31 pressurizes the tank through the carb and was doing so on the first flight of the plane. On the second flight the engine quit and I ended up doing an off field landing. Brought the plane home and did some minor repairs to the wing. The next time that I went to the field I couldn't get full RPM from the engine so I brought it home again and check all of the plumbing on the tank as well as cleaned the carb.

I'm now getting 5700 rpm with an 18x10 prop but the fuel system is drawing a vacuum, not pressurizing. Checked the carb again and everything seems in order. Does anyone know what I'm doing wrong?

Any help would be greatly appreciated.

Happy flying,

Jim
