Re: New Thread! Replacing the Carb on a 351e V6?
Most of the time this is caused by a lean condition. Some crud in the carb or an accelerator pump problem. But I see a lot of soot in the top area of the carb. So I think you have an intake valve that is adjusted to tight and is leaking hot gas back into the intake and ignighting the incoming air fuel mix. This is always more pronounced at low vacuum at WOT. The valve lash hot is .012 intake .018 exhaust .
