RE: [T3] '70 square tuning

["Adriel Huntington Rowley" <architect_7@hotmail.com>]

Well, I also want it to match also.  The old one is fine, but apparently the
person (Tom's Master Mechanics at 5820 Autopart Mall San Diego, CA 92121
(who also specializes in Audi and Chrysler)) did not put the distributor
dive in the engine correctly and the drive dog was slipping.  I was told by
the P.O. that this can happen if you hit the cam when assembling (which
already does not sound good to have the cam off).  Volker apparently made an
adaptation so the drive dog on the Type 4 distributor would not keep
slipping.  If I was to change it, I could no longer dive it.  I would have
to tear down the engine, but I do not have the time, money, or knowledge
(what happened to the days of my Father where help was at hand?). 

Why would the vacuum not work?  I have the one on the Type 3, would that
work on the Type 4?  I am not getting which does not work.  I am tired of
bashing my teeth (I already have a bad jaw from smashing it on an auto
lift).  Also, gas is not cheap (especially hear where it is the highest in
the country) so I want to get the best.


Thanks,

P.S. The engine also runs like one of those radials not on all cylinders
during the five minute warm up (shaking, rattling, and just plain making a
racket), so maybe the next thing should be a rebuild (even though it has
30,000 miles).  I have a spare case...is there a part list out there for a
rebuild?  And where would you get some of the specific parts?  What would
this cost?

This is on a type 3 engine, right?

In any case, you don't NEED a vacuum advance, but you'll get better 
fuel economy while cruising if you have the right one.

The type 4 dist came with vacuum advance, and maybe a vacuum retard, 
too, but there's no point in looking for a replacement for it, 
because it won't be matched to the vacuum port on your type 3 engine. 
Remember, I said you can't mix and match.

What you really ought to do is get your type 3 dist repaired and put 
back in. Then you'll have a properly matched system again.
