Please advise:

82 2.0L with orig type distributor.  I bought the Van with an 009 installed.
Never had any troubles.  I convinced myself, though, that putting an original
205 back in was the right thing to do.  So I bought a remanufactured 205 and
installed it.  Ever since(4 months), I have had minor troubles.

Tonight I set out to verify the timing, should be at 7.5BTDC.  I am using the
static method Muir professes about.

Before any adjustments I checked it and it was at 16 BTDC.  Ok so I fiddled
and got it perfectly to 7.5BTDC per the static method.  Start it up, adjust
idle a hair, and all is well...

For shits and grins I check timing again: 20BTDC.  A problem!!  I restart it,
run it 30 secs, shut off.  Timing at 10BTDC.  Restart, 30 secs, shut down, 4
BTDC.  Restart, 30 secs, shut down, 10 ATDC.

Is this remanufactured distributor "bad" or am I missing the boat?
I still have the 009 and am ready to install if need be....

Thanks folks,
Paul
