1966 Dart 225 with Holley 1920

Jayman62 said
I'm having an issue raising idle on my 1920. I have the idle adjustment screw bottomed out on the screw spring so so can't screw it in further. I need just a bit more rpm to stop it from stalling when I put in gear. Could the timing be off? I have it set about 2 degrees btdc. Fill confession, I did the rebuild of the carb, other than the idle issue only other issue is a bog if I jam the pedal from a stop. Otherwise it runs fine. Only issue during rebuilding was I coyld not get out the checkballs.View attachment 1715761728

Thank you for any advice.

This is one for Rob! My initial thought is the carb is way too rich if you need to bury the mixture screw. Checkballs should easily fall out. If they don't, then gunk is keeping them stuck and that should be resolved. Also, 2* before is way too little. Your poor lil engine would be much happier with more timing, and that would resolve the stalling problem.
