Just tried for a second time-Perfect idle upon starting.

Finally I can go to sleep! Up for days on this thing-obsessed.

It only blows smoke if I romp on it when its cold, at idle its good. The choke is still a little funny, it stays all the way closed at cold start up which is too much. So there is a piece of 12 gauge wire wrapped around the center air cleaner bolt then one leg of the wire going into air horn to prevent the choke from closing all the way when its cold. Its the perfect amount. I was thinking of trying to adjust it but I would have to grind off the choke cover plate to gain access and that seems like a headache.

ragragtimtime: I thought I read somewhere that the choke unloader is supposed to pop the choke plate open just a crack upon cold start to prevent overenrichment. I don't believe this is working. When I try to peak around the cover it looks as if all of the parts to the unloader are there, just for some reason on cold start choke plate wants to slam all way closed. Do you think if I take it apart and adjust it one tooth like you said it would cause the choke to not close all the way? If it might work, then I'm all over it. I am happy with it but I have been told i have OCD.
