Gregg, mine gets better when it warms also. Until it warms what does yours do? What carb and tuning did you do? Thanks, Don



When it's cold, it acts like a cold engine with no choke, no big deal. I had to re-jet, reduce the main air bleed size, reduce the idle feed restriction size, and open the power valve channel restrictions. Doing any of this without testing the A/F ratio is like shooting in the dark.
