You need to take the throttle bracket back off and re index it on the throttle shaft that sticks out of the pump top. I can't think of which way it needs to go right now, but do it so that when in the new position it acts like you are pressing on the accelerator. Go one spline at a time until it's right.

The VE pump is really simple once you understand how it works.
A word of caution when working on you pump, especially linkages and the governor.
Always have a way to snuff out your engine in the event of a runaway.
It can turn your engine into a pile of scrapmetal instantly.
