OK, Pull the valve cover so you can see the valves for number 1. Rotate the crank until the mark on the balance lines up with timing mark. Make sure that this is the overlap TDC where both valves are open. If the intake valve is open more than the exhaust valve, the cam is installed to far advanced.

Stan,
It runs too good for that to be it.

Curious if it does the same thing if you roll up and then beyond that RPM, but aren't standing on it??

I'm swapping the carb off my old plow truck. Same carb just old, dirty and off a Chevy. Feels wrong. lol
Then I will take a test drive with a video and it will be easier to see what's going on.
