Yes I don't know I can't keep mine running even ideling at 1000-1200 . Stalls and is so very inconsistent . Can't find a vacuum leak . All hoses are off and porttw plugged . Get no rpm Increase spraying carb cleaning around intake
One issue Ive always had with tuning carbs is getting the idle screw back to "base" where the engine is running off the idle circuit, & not above it. Back the idle adjuster screw all the way until it is not touching its stop. Screw it in until it just touches the stop, then 1 more full turn. Start engine, what does it do?
In my love/hate journey, I found out the Accelerator pumps felt was drier then Betty Whites Muffin, & it would always stumble off idle due to this. Hence a higher idle rpm to bypass that stumble. Tried a new one, got better, but still wasnt what I wanted.
This is also a great time to ask our group to lock down how many turns the idle mixture screw is to be turned out from fully seated? 1 turn, 1 1/2? 2? whatever works?
Personally, I finally gave up on my POS carb & bought a newly remanufactured one. End of carb headaches
