Subject: Re: 1969 engine runs very rough by Durango_Boy on 2011/10/15 13:18:09 Bill nailed it so far...the best route to follow is your fuel system for starters. Pull each plug keeping track of it's location...which cylinder did it come from. Record each plug's color, and if it is wet or oily. By the way, white is lean, black is rich, brown / dry is perfect, and oily indicated a whole new set of problems. If you have rich condition plugs on both banks then indeed it is getting too much fuel via the carb. If you didn't change anything else when it was parked then I agree it's a needle / seat or float issue. How long did it sit? Have you tried a fuel system cleaner? Clean all plugs and run it with some Seafoam. |
