Carter yf 2100 ---- bog off idle - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have eliminated the ignition, timing, valve operation, fuel, float level and all vaccuum leaks. I have rebuilt the carb and cleaned every port , jet, etc. The squirter works. I have pulled it off twice and double checked the build. The ports on the bottom are both exposed to vaccum.

It starts and idles exceptionally well. Timing is set about 5 btdc. The advance works -checked with timing light. All plugs are firing. New HEI.

I believe the bog may be from shaft wear or carb is somehow not suited for a 235.

Anyone have any ideas of what I can further check. Or who can fix the throttle butterfly shaft clearance?
