Ok i just installed Idle screw for the tors removal, put on new cap. Now it won't idle. Like i kick it, it revs normal, but when i let the throttle off, it dies?
I bet you don't have the idle screw that you just installed in far enough. It has to be screwed in almost all the way to make enough contact with the throttle slide to hold it open at idle.
BTW, which side of the carburetor did you put the screw into? It has to go on the side with the fuel inlet; otherwise it won't work.
