I get the idle to be around 1000 RPM (big cam)
I looked at the timing and it is 20 degrees (engine builder recommends this)
5 minutes later, the idle drops about 50-150 rpm
I check the timing and it is now 10 degrees
I increase the idle back to 1000
still 10 degrees
I set it to 20 degrees and lock it in again
I rev to 3200 and get onlt 28 degrees
Back to idle, but now it's around 1100
timing is at 24 degrees
no matter what I tried or what springs I use, it never comes back down to the set timing. and it takes about 5 minutes for it to come down any degrees
I called MSD and they had me check the bushings under the weights and that it all moves freely, and it all moves just fine and I even dapped a little oil on the pivit areas and no difference.
Do I just have a bad distributor (only 800 miles on it)? Anything I'm missing? |
I've pretty much had the same thing with mine, car doesn't get used much and I find the MSD distributor is prone to moisture build-up and rust inside.... I generally take mine apart once a year and clean it out real good and put a dab of
oil on all the moving parts/springs, not much,just a dab, seems to help......
You might also change your springs, sometimes when a spring loses tension, it takes forever for the timing to return to the base timing as you stated yours does.
Your not alone...........
My MSD unit has 22 degrees built in, so I only worry about total timing, my engine runs best at 32 degrees total, so that's where I set it at 3,000rpms, and let the idle timing fall where it may, in my case 10 degrees........
Your engine builder recommended 20 at idle, what was his recommendation for total timing?????
What are the specs on your engine.....?????
