Re: Ultramatic throttle linkage adjustment

You really need to check the bottom end too just to be sure the geometry you are relying on for the rest of the linkage is correct. Once that has been verified go back to the top and see if it still wants to be where you have it. It may be OK at the bottom and the car will do well with where you placed the top end but throttle linkage adjustment is so critical on an Ultra. Among other things throttle linkage controls the amount of clamping pressure applied to the high range clutch plates. If a misadjustment allows those discs to rotate against each other a burned high range clutch happens very quickly.
