Engine stubbles at idle speed
The MH in my signature has become Ihard to start and falls flat when I give it the gas. The problem seams to be progressing. Changed fuel filter before trip, ran can of seaform. Still does it when it'...

You should not see more than 300 ohms on any wires. Lightly pull and twist the wires as testing them, as their may be bad areas on the inside. Bad wires usually do not show up at idle, as it only takes about 5,000 volts to fire the plugs. As loads increase, it will take more voltage to jump the gap, and that is when bad wires show up. Has anyone put a timing light on it? IS the timing jumping back and forth more than 5 degrees? Check slop in the timing chain by turning the engine forward until you see the rotor start to move, then turn the engine backwards until you see the rotor move the other direction. If it takes more than 10 Degrees of movement at the crank pulley, it may be the timing chain has jumped a tooth. Keep plugging, and let us know what turns up.
