I cannot get my Saito to run right. Throttle is wide opened and I can only get up to high 3000rpm. Lean in and lean out and still it does not get to 6000 rpm. When I broke the engine on a bench it was running fine at high and low rpm. Initially, I thought it was because I had the fuel tube too long inside the motor box and the carb pump could not pull the gas. So I shortened the tube and it kinked so no fuel to the engine. So I decided to run the part of he fuel lines outside the box so it will not kink. Yet it still cannot reach optimal high rpm. What am I doing wrong? Please help. Thanks.
