Wow! Thanks guys, AC delco r44t gapped @ 35. Automatic 350 w/2400 stall. Negative on the vacuum gauge to set idle. Checked for vacuum leaks around carb base but not distributor. Have a Holley book but not that one. Booya on Flyers! I set my idle with the idle screw, closed my air bleed adjusting screws completely. So far no run on/backfire. Doesn't seem right though.
