Quote: What is the total timing and at what rpm does it come in at? I would bet it is to much or it is to much coming in to fast. Put a light on it and see how much it has at 2000 rpm them 3000 rpm. I never bother with initial timing on a performance motor, you are much better off setting the total timing.
good luck scott
I moved the timing to about 12 btdc @ 2500rpm. This didn't have much effect by itself...however...since there were many suggestions that I was too lean...I backed the A/F screws out as far as they would go without coming out of the carb. This has reduced the surging alot but it still does it. we are getting closer.
