Thanks for the advice guys. I'm still trying to understand. So when its cold it needs a richer mixture right and when its warm its too rich. I should be able to tell by the plugs too shouldn't I. Some people have told be it might be a cracked base plate or a bad bushing in the throttle shaft. Could this be true, is there any way to test this out. Cause I probly won't be able to see it with a naked eye. Also how do I check the power valve and how to check if I have valve binding.
