lately I have been stalling when coming to a stop or upon aplying throttle from a stop on my non-cc qjet 350. I notice that I have hesitation whenever I apply big throttle changes but I thought that might just be the air valve spring which I have yet to tighten.

however this idle problem sucks because It will stall right in the middle of the road if I have to stop for too long.

I leaned the idle mix screws cause I thought it might be rich (loading up at idle) and that didnt help. I have adjusted the idle stop screw when the engine is warm and also the mixture screws but this problem remains wherever I set them.

thanks for any help.
