<VV> New Clutch Isnt Working

[Steve Brennan]

Lon, 
Do I understand you to mean I should put the car on the ground and do the
same test?  I attempted to do the "burn in" with the car on stands, but with
the emergency brake on.  Is this not sufficient?  In any event, how many
"burn ins" is a reasonable amount?  I just did about 4, letting things cool
off for a minute or so between attempts.

As for the parts, I got everything from CU, as I purchased your clutch
superkit (w/Dale bolted flywheel) in Nov '06 (Invoice #3537), but I was one
of the folks who had to wait a while for Dale to produce more flywheels this
past spring.  During the wait, I decided to go with the Kevlar clutch, which
I purchased from CU in 4/07.  Upon doing the installation, I did notice that
the bushing fit on the shaft nose rather tightly, so I worked it off and on
several times and "pressure-oiled" it up well, per the books.  That said, I
did not anticipate this issue, so did not use an emory cloth or take any
similar action, which I now wish I had done.

In any event, is there a way to confirm that my problem is caused by a tight
bushing before I pull the drive train back out?  As frustrating as this has
been, it will pale by comparison to dropping it all again, only to find it
was some other problem that was repairable with the drive train in the car.
(Again, this is a Spyder, so dropping the engine is a bit more of a hassle
than most Corvairs.)

Thanks for any and all assistance/advice that is offered.
Steve

Steve - NEVER NEVER NEVER assume that you have an engagement problem by 
testing it with the car on blocks. It only takes the slightest amount of 
tightness to make you think that the clutch will not disengage! IT IS 
NOT A REASONABLE TEST!

Did you replace the flywheel, pressure plate etc all as one unit from 
the same supplier? Where did the Kevlar disc come from? The ones we sell 
do "burn in" but that has nothing to do with the clearance, it has to do 
with burning off some of the initial binders in the Kevlar assembly. 
YES, a tight pilot bushing will cause this. Did you replace it? Lon
