Re: Hit & Miss Ignition
you need the tim light on the first cylinder, at the fan end of the engine, as you likely already knew. if the engine is missing, you'd feel it in the way it drives. even if a valve were burned, and causing a miss condition, if the ignition were still firing properly you would not notice a miss in the tim light. my guess is that you have a weak connection at the tim light, causing the light to occasionally miss. try it on another cylinder. you can't set the tim mark that way, but you can test the tim light. if you have a pal with light you might want to compare with it on your engine. does the engine drive like there's a miss?
