hey guys
I have a classic fast on my NA healthy bbc. i started playing with adding timing and leaning out the mixture at cruise. The engine really seemed to like the increased timing. But, after about 10 minutes of driving, i came to a red light up ahead , so i let off the gas and got 2 big backfires and the car died. had to cost to the side of the road.
any ideas if the lean mix or the added timing could cause backfire on decelleration?
Is there a set of example VE, timing and AFR maps anywhere for these classic FASTs (BBC preferred)?
thanks
