Still no luck on getting some top speed out of it. Tried to swing the distributor back and forth. No luck. More timing it was wanting to backfire through the carb less timing it bogged and barely hit 45 mph. It's been running fine since I swapped the primary idle jet. It will run up to 3500 4000 rpm in first thru third gear but as soon as u go into fourth about 2500 rpm is it and in fifth with the pedal to the floor 2100-2200 rpm is all it's got. I'm gonna swap air filters to see if that will help some but it has a k&n that I cleaned and oiled as soon as I got it.
