Dart Clutch Adjustment Problem
Here is what I do know. If you replace your Borg and Beck pressure plate with a diaphragm style (like Centerforce), you have to remove your over-center spring. That spring might be depressing the fingers of the diaphragm pressure plate causing your problem.
When I adjust my clutch for the first time, I usually loosen up the adjusting rod until the throw out bearing is just able to wiggle off the pressure plate fingers.
