Didn't think of that one yet. Glad you found it.
You said you have replaced the mixer but is it working correctly? Looking into the barrel while turning the engine, it should pulsate.
Have you measured engine vacuum at an idle? Or engine exhaust back pressure? Engine timing with a timing light or verified by timing marks? Ive seen restricted exhaust and incorrect timing cause this problem in the past.
I have taken the vacuum lock-off off of it and replaced it with an electric one to try to eliminate that possibility. That didn't change anything.
Does it look like that vacuum switch goes directly to manifold ? then just jump that out and see what happens ? maybe it is defective ?
One component not mentioned is the lock off. If unit has vacuum lock off, it can be causing this issue. Will it run if you remove the air filter?
Yes I did. Everything looks good on compression. Also did cylinder leak-down test. No problems there either.
Have you done a compression test? Low compression can cause the engine to not draw enough fuel to run until choked.
