I am STILL working on my "won't idle in drive"problem.Think I might have found something.If I set the initial timing at 8 BTDC with all vacuum DISCONNECTED that should NOT change if it is put into drive? Yes or No? It is idling at around 700 which should not bring the centrifugal advance into play.Put it into drive-timing drops to 2 BTDC.Hook up the fulltime vacuum line idling in neutral timing is 18 BTDC.Runs good.Drop it in drive-dies.Increase speed on carb so I can at least check timing in drive.It has dropped back to about 13 BTDC.Engine vacuum has dropped from about 18 to about 13.This distributor was an exchange 57+ last year.If the timing is retarding as I slow down at a light for example as it is doing at idle-would this likely be the cause of my poor idle in drive?Going to pull the distributor for a look inside.What should I be looking for?This change in initial timing does not seem to be normal I don't think?
