It had been running rich and with a rough idle, tried everything cherry bomb, msd box nothing helped. Has pipe, filter, and high compression piston. It sputtered on idle and ran ok as long as it wasn't idling. I took off the fuel filter, now runs a inline filter. I took spark plug out and it gets a one spark for about 100th of a second, and no gas. I metered the fuel pump injector and they all read out good. The only thing I can think is electrical, but what? Is no spark signaling no fuel or is no fuel signaling no spark? I put it on the suzuki dyagnostic machine and the only code read was the tip over sensor? I checked that and metered 19.5 ohms and it read ok. Or is it fuel related.

Help Please.

Sure do miss the carb. days LOL.
