Okay, so I don't post often enough for everybody to know all details, so. . . Good news, I cured the stalling while engine cold problem I've had for 4 years by using carb cleaner on the ICV.(nasty). Anyway cured the stalling problem, but now I Idle at around 1100 to 1250 rpm. I've seen some stuff about a small screw on the ICV to make very minor adjustments to the Idle, but if anyone has any other ideas for getting idle down to 750-900 I would appreciate it.
