Pretty sure I'm on number 1 compression stroke. ( stuck a piece of tissue in number 1 plug hole and cranked over engine until it blew out.) Are all number one positions in the same spot on a distributor cap ? Do you think the carb could cause this ? Its an Edelbrock 750 with a mechanical choke. I've just installed guages so I could have a tach and vacuum guage to tune it with.

Please give me list of thigs to try tommorrow.
