[T3] conversion back to fi a success - status update

[steve crispino]

As I mentioned to Dave, the car doesn't have all that much power.
 Investigation has shown
that the mechanical advance on the distributor is not working.  The cam is
not freely moving
on the drive shaft.  Once disassembled, I was able to get it freed with a
some PB Blaster and a
bit of manipulation.  However, I'm doubtful it will loosen up enough to
make it operational.

My thought was to pull the cam off the drive shaft and polish the corrosion
off.  However, there's
a pesky little circlip at the top of the shaft for which I do not have an
obvious removal tool at my
disposal.

I'm still under the gun as it has to make it to our 22nd show this Sunday.
 Any suggestions?

Yes, that's a huge difference.

There's no diaphram in the '69-9 PS, only in the middle generation
'70-1s, but the lack of epoxy means that it's been tampered with. The
tampering, plus the air leak, should make the rest of the difference,
at least after it gets a fresh tuneup and valve adj.

I can recalibrate it for him if he's interested. I reseal the screw
afterwards and that should give him a good spare.

Good, otherwise he'll be looking at an unexplained problem a couple
months from now.
