Good Evening guys and gals I need some help, I have a GS Racing 1/10 scale car with a GS15 engine. I can get it to start with some fuel in the carbi and it will idle until the fuel runs out of the carbi then it stops. I have cleaned the carbi so that it is free flowing and I Can push fuel through the line. I feel as though it is not sucking fuel through the line. Could this be true? Or does anyone have a different theory. Please help cheers
