weber runs great while driving but when in nuetral or taking off, it doesnt like low rpms. when i rev it from 900 rpms (unloaded idle) it does fine, but when the rpms are dropping, they drop about 100 or 200 rpms below idle and then slowly comes back up. when i take off i gota keep the rpms up a little over idle to keep from trying to bog or die. ive went trough tuning the carb and its as close as its gonna get, and doesnt change the symptoms. my dizzy may be off a tooth as it is tilted all the way toward the fire wall. but ran best that way with old carb. would even idle smoothly at 400 rpms. so im thinkin either i got a leak at one of the gaskets or the weber is just more sensetive to timing than the old carb. any thoughts?
