Alcohol Dominator question

pro system alcohol dominator that I bought used. Sent back to pro system to refresh long story short the car will die when I put it in gear. Any information will help. Can’t find any vacuum leaks. Thanks

Thumpr carbs. Dominic. Find him on face book.

How many turns out are the mixture screws from fully seated? What size are the idle air bleeds?

Turn all four mixture screws out one full turn to see if that helps
Are you using both idle speed screws evenly, equal amounts of turns, to set the idle speed? If not try that also

dont contact thumper carbs he only does gas carbs,no alky or e-85

this is for e-85 can try this

My bad. I forgot about Dom not doing alcohol based fuels.

Don’t know much about dominators but I do run methanol via carb

What fuel specifically are you using?

Is it on the idle circuit ?
Or is curb idle turned up to high?

What’s your timing situation?

How radical is this engine? Cam , compression etc.

This setup all works well with a different carb?
