I'm using the bushing from 4 second flat 10*. So I have a lot of initial 25 with 34 total. Now I just need to get a friend to stop by so it can be checked whenever I drop it in gear. Then verify when it's all in. Then play with the springs some more. Sprayed starter fluid all around intake and base of carb no change in engine. Only 1 vacuum line for pcv. Fast you're exactly right, I try not to idle it around and do the neutral bump, but I also don't want it stalling after I do my burnout as a courtesy to the other racers.
