I need to check the wear on these shoes as I have about 12 tanks on them. It did seem that maybe they were starting hang up on me in the Main last Saturday. My car did not seem to idle down as quik when I let off the throttle.
So you are saying to run the alluminum with the gold spring and the carbon with the black springs. If so thank you very much.
