Hi, I would like to know if anyone has a factory service manual for this motor Serial #0C140802 or if you know where I can get a used manual ( I have the Selco manual it does me no good to vague. My problem is week spark on top cylinder causing the plug to foul I think I need to replace the switch box the coils tested good. I used a spark tester and got no spark to jump the gap so I switched coils and got a spark the engine will run with the week spark intermittently.
