i have a 430 and have had a lot of points problems so i recently got a pertronics ignition with a flame thrower coil. i put it all on and timed it by ear and it ran great for a while 15-20 minutes then it started losing power and got so bad it was almost gonna die and it was at full throttle. then at idle it was backfiring which it never really did before. i have played with the timing and the carb adjustments all evening and overtime i get it right on the high end it doesn't idle right and vice versa. any help. not sure how to technically time it as my light does not seem to work on 2 clys
