Mr fixit

The stumble is only when I accelerate and hit that prox 2000 rpm point. It does not seem to do it during rapid acceleration just when I "try" to drive normal, constant easy pressure,hit 2000 then stumble and launch.

Where is the transition slot located? I have taken the fuel bowl and the metering block out and cleaned them with carb cleaner.
Thanks for the replies

Oh when I hit the stumble the vac drops aprox 2 to3 inches. Hope the info will help
