Sounds like it's going lean as soon as the choke comes off. Try adjusting the choke a notch or 2 richer and see what happens. You may also have the idle mixture set on the ragged edge of lean so you may have to tweak them out a 1/8~1/4 turn.
I did play with the choke but the same thing happens even pulling off
later but I haven't pulled the screws out too much. Maybe I'll give them
a half turn and see if that helps. The darn thing is the 750 I had on it
was perfect cold or hot, that's why I think it's this carb. Both had
electric chockes etc. I have hear the street avenger carbs tend to
run really lean so I tweaked jets until they were good but the cold
idle problem is stumping me. Is there a difference in how they handle
air in the idle circuit?
