Got my Puch w/ newly installed Amal, 70cc cylinder-piston and biturbo running, but the engine idles so fast it's going to drive my neighbors crazy, plus it's running the rear wheel at at 10-15mph while on the center stand.
I backed the idle screw as far down as it can go, no drop in the idle speed. The mixture screw also seems to have no effect. The choke as well seems to make no difference. And there is slack in the throttle cable. Any suggestions for other steps to try?
thanks in advance,
