Double check the idle screw.....polish that mofo till she shines. ive been down this road with sticky carb's before and it sucks ill tell ya that.

Thanks Integra, I did pull the idle screw. It was gouged from the carb slide, I smoothed it out with some scotchbrite between my fingers. It helped a little. I have been researching the picco carb sticky situation and see this may be a reoccuring problem. I'm going to file the carb slide slot and see if it helps.

a polishing bit on a dremel w/some compound or a big 6" polishing wheel make's quick work of little idle screw's...also check the carb body itself to make sure the bolt has not gouged the inside...you can clean that out with a rubber bit.
