Vacuum Advance problem



Kerry,
Some Mopar vacuum biscuits are adjustable! There is a tiny allen screw 
accessible through the tube where the hose attaches. Years ago someone on the 
IML 
posted a link to a web page with a whole dissertation on how to adjust timing 
and those vacuum biscuits, but I have since lost it.

Friday.  Got all 4 power windows to work after rebuilding two motors and some 
tlc. 
 
 I then drove the car for the first time other than around the block when I 
did the trade.  It did fine except for a rough idle and slight stumble off 
idle.  
 
 This morning I decided to do a quick tuneup and in the process of checking 
the timing, I realized the vacuum advance was not working.  Could not find a 
vacuum advance at any local shop but Autozone had a complete distributor for 38 
bucks.  Put it in and the car idled great but pingged like mad  Messed with 
advancing and retarding the timing, setting dwell, all the tricks I knew.  
Nothing worked.  Push the gas and it pings and rattles.  Messing with it made 
it 
better or worse but nothing made it go away.
 
 So I called the Doctor. (Robert Soule) who told me the new distributor 
probably had the wrong vacuum advance unit for the car and was over advancing 
the 
timing.  So what have I done?  Disconnected the vacuum advance and set the 
timing at 16 btdc.  It runs fine but has the same lumpy idle as the old 
distriubutor did.
 
 Anyone got any ideas?  Where can I get the correct vacuum advance unit?  
None of my parts houses show them.
 
 Also going to have to do some work under the dash.   No power to the fan 
motors or antenna switch but the antenna works if you jump 12V direct to the 
wires.  Also the EL dash if flaky.  Nothing on the needles and the guages are 
dim 
and the switch has dead spots.  I'm still doing the "Dick Benjamin boogie" and 
twisting the knob so perhaps it will break in.  I"ve got a spare instrument 
cluster and EL transformer.  Makes it kind of interesting to drive at night 
though.
