I just did some rewiring and carb and fuel pump cleaning on this engine. If I accelerate quickly, it bogs down and shuts off like its not getting enough fuel. However, if I slowly increase the speed, the motor feels like it "catches up" and runs fine at full throttle. The gas is fresh and the vent is open on the fuel tank. The plugs are new too.<br /><br />What could cause this problem?
