machine gun backfire @ 1/2 - full throttle


Recommended Posts

ok, next issue, i now have all 4 cylinders firing after having to replace 2 ignition coils. now when i open the throttle up past 1/2, it sounds like machine gun going off and it refuses to accelerate any more. i've synced the carbs, and tried the idle mixing screw. tried at range of 1 1/2 turns out all the way to 3 at 1/4 turn increments. once again, all help is appreciated. one thing while i noticed was the main jets were not set up like i've read on here. the PO had 122.5's on the right side vs the left. so i switched them so 122.5 on the left, 120 front right, and 117.5 back right.
