[DeTomaso] Pandora question

We can probably rule out that the dampener may have slipped.  Chris is using
a BRAND NEW Pioneer 872027 SFI approved damper available here at Summit:
http://www.summitracing.com/search/?keyword=PIO-872027&dds=1\

And further described here by the manufacturer
http://powerbondparts.com/

I'm using the same damper on mine.  They are very well built and when I
checked my TDC pointer it was within 1/4 degree of correct!  I'm using the
same early 70-71 style pointer as Asa Jay's but I believe Chris is using the
later style pointer that spans across the front cover.

I still recommend that Chris check TDC accuracy as his next step and mark
his damper so he can detect if it slips in the future.  Further spirited
driving will easily uncover a slipping damper.

Good points--

1) I haven't yet done the tdc check yet; I'm waiting to borrow the correct
tool from another club member.  I'll bet, however, that when I do, the
pointer will be pointing exactly 16 degrees before the magic marker mark on
the damper.

2) I sent Doug Braun the number of my balancer, he researched it, and it's
the same one that he is using, and he said it's absolutely correct.

There are two mounting holes on the left side of the the pointer (which is
its own bracket), and only one can be used at a time.  Right now, the lower
hole is the one with the bolt holding it in place.  I don't think this will
work, just by looking at how things are set up, but I'm going to try and
loosen the single bolt on the right side (which only has one hole in the
pointer bracket), remove the bolt on the left side, then move the bracket
down and reinsert the bolt through the upper hole of the bracket.  That
would lower the pointer , and it looks as if then the pointer will be in the
right place relative to the damper and timing marks.  Unfortunately, though,
I don't think it will work because the pointer bracket is shaped in such a
way that I don't think it can be moved down.  It's worth a try, though.

It does make you wonder why the pointer bracket has those two holes on one
side with only one being able to be used.  It was mentioned in a prior email
that there are a number of different pointers that can be used, and I'm
beginning to suspect the I have the wrong one.

Chris,
Interesting.  Sounds like that is the way it was done at the rebuild??
Perhaps the wrong? balancer was installed.
When you did the TDC check, exactly where was the timing pointer (on the
front of the engine) pointing (relativeto the TDC mark on the balancer)?

some problems that seemed non-timing related.  When I got caught in the rain

sitting in the garage and drying out for a few days, it then started fine.
It sounded like either an electrical problem (water in the distributor, for
instance) or perhaps water in the carb.

After Stephan had taken off the carb and discovered a number of issues with
it, he put it all back together and that's when he was going to adjust the
timing and the strangeness was observed.  Until that time the car had run
fine, unless it was wet, in which case it sometimes wouldn't start.  This
also is more evidence that the damper is probably not slipping, since if it
were the black magic marker mark probably wouldn't still be the mark at
which the car runs best (which it is)--slippage would have caused the magic
marker mark to be at some random point, not lined up perfectly with the
pointer , when observed using a timing light.

Sincerely,

Chris
