Bogging down, hesitating, stumbling from a dead stop and when accelerating at speed are indications that the accelerator pump and its check valve are defective.
But I doubt these parts (and the pilot bearing) are causing the problem.
Oil on the flywheel/pressure plate/clutch disc caused by a rear main seal leak, greasy hand prints on the clutch disc, worn clutch disc/pressure plate, warped flywheel will all cause "clutch chatter" the usual term for your problem.
Once a flywheel is warped, turning it down will not solve anything, because once it's warped, it's warped forever.
All turning it down will do...is remove the blue heat spots, but these will re-appear within a short time.
I doubt the power valve has anything to do with your problem. It's clutch disc/pressure plate flywheel related.
Hey Bill,
The clutch disc, pressure plate and rear main seal were all replaced with my tranny rebuild. They did have the flywheel resurfaced and drive shaft balanced. As far as greasy hand prints, I cannot tell you for sure except for the flywheel.
Really, the only time I notice the issue is from a dead stop. Once the clutch is completely released it stops doing it.
