I kept fooling with it and finally got it. I had taken it off my kart and put a new hemi on. I put fresh oil in and and ran it three times varying throttle position. On the third time I raced it up of the factory setting. About 3600 rpm. I started backing in the throttle stop screw. Ended up backing it all the way out. Tight at 4900 on the stand.
I think instead of moving the the position of the spring I may just tie wrap a few of the coils of the spring and see if that raises my rpm some. I believe I could also change holes in the governor arm to raise the rpm a little. I want to try for 5300. We have a 5500 rpm rule. Going to work with it tomorrow.
