Timing answer for 2013DartR
« on: March 26, 2015, 06:38:03 PM »
I can't answer your question in a PM because your inbox is full!

Move the vacuum advance line to the "air cleaner vacuum" port on the Holley.

Should have put it my last pm but when I was setting the timing I also moved the vacuum line where you told me to. I didn't realize I was only allowed 1 message. I guess because I haven't posted just lurked and tried to learn.

Next question: You are setting the base timing with the vacuum advance disconnected, correct?

Yes but there doesn't seem to be any difference whether it is connected or not. Will the engine speed change when I connect to vacuum advance line after timing?

What should change is the timing value you see with the timing light.  The mark should move way counterclockwise.  About 15 degrees' worth.

are you unhooking the hose then plugging the end of the hose with a golf tee or a nail?

FlatBlack77 - Yes, I am plugging the vacuum line while timing.

Rich - Will the timing mark move 15 degrees while at idle as soon as the vacuum is reconnected? If so that is not happening. When the vacuum is attached the timing mark moves under acceleration but it also moves the same amount with the vacuum line detached and plugged.

OK, so the vacuum advance isn't working.  You should be able to watch it move 15* counterclockwise when you hook up the hose, if you have it hooked to manifold vacuum.  Check that the hose isn't split or something, but it may be time for a new distributor.

I'm with Rich. i had trouble with my trucks timing and it turned out the vacuum advance wasnt working AND the mechanical advance was totally shot.

$30+ for a new vacuum advance from AdvanceAuto orrrrr $90 for a whole new distributor.

i got this one and its nice for the money and free shipping.

it will eliminate any questions about the distributor being bad ya kwow

Well, the eBay ones are more in my price range. I was looking at the red one and it mentions a 4 pin ignition module is this some I need to be concerned with? Also, how do you set up an adjustable vacuum advance?

Went to install the distributor today and I've got problems. Apparently mine is a 5 pin ignition module which has its own set of wires leaving the distributor straight back to the firewall. The distributor that I bought is a 4 pin and has no use for these wires. Now what? Can the Electronic Spark Control be abandoned? It doesn't appear to connect to anything except the distributor and detonation sensor.
