After reading your post concerning how you set the PMS reminded me of something we used to do to our race cars setting the idle and fuel air mixtures consecutively until you reach an equal point between the two. I'm going to give that a shot tomorrow after work.
The pilot needle is set in the 5th grove, and I am using the 172.5 main jet, due to running straight pipes and a low restriction air filter.
I am going to go through it another time using starter fluid to be sure there is no vacuum leaks. Between the best setting for air fuel mixture and vacuum leak it has to be one or a combination of the two.
I'm sorry, it does say 3 1/2 turns on thew barons sheet, I was looking at Shanes instructions. I had both of them sitting right here at my desk. Wonder why his says 2 turns???
Hope you get it sorted out soon.
