Air Bleed Alternatives

Totally agree that not a good idea to just go ch anging stuff. As far as idle being rich. Tailpipe is an eye burner at idle. Plus I have to open throttle plate way too much to get engine to idle and that is at 22 degrees initial on the timing. Also mixture screws are about 3/4 turn out and really not big change with any adjustment. I will install the new carb and run first. No changes. Then check plugs. I have a good article on reading tqve plugs. i will also read the article you provided. Thx
