==========================================================

For those of you who have been following my no start problem, I think
the situation has been rectified by the replacement of the rotor.
 
While having the distributor out of the car, I decided to have it put on
the Sun machine to see how it was performing.  It is a Mopar Electronic
distributor and is run with the vacuum canister blocked.  It's in a 360
engine which runs 12.8 compression, .508 Comp Cams hydraulic camshaft.
The engine is in a 66 Valiant race only car.
 
Here are the status:

That said..what does all that mean?
 
Where would you begin setting timing at idle in order to get the correct
34 or 35 deg that I have heard mopars like to run?
 
Any input would certainly be appreciated.
