So...I changed the carb, tuned the idle to 15" of vacuum with all four mixture screws at 1/2 turn out and still have the same problem! I pulled a plug that was brand new with only 1 hour of run time and it was black and sooty. The soot is damp and can be wiped off with a rag. I'm now thinking I may have the same issue Chris was having with the valve seals. The problem is that I can't road test the car as it falls over as soon as I give it gas. They are easy enough the change, but still are a few hours of work. Before I do that does anyone have any other suggestions? And Brent if you are reading this thread, would you use these seals?
