Tim, is the power valve working? and what size of main jet is in it?
There should be a small check ball in the bottom of the accelerator pump inlet from float bowl and a larger check ball in the outlet side. I have seen them mixed up or even put in the power valve under the long spring, also make sure the long spring is in the right place. I wouldn't get into valve timing yet.
Do you have the external adjustable main jet on that carb?
