    Default Timing Problem

    What would cause the timing mark to jump +/-5* when checking it with a light? The distributor is a MSD Pro Billett 85551.

    Does the tach read properly and steady also? I just had a msd box that was causin mine to do the same thing, every now and than it would be normal for a second than get real eratic. I ended up changing the box and solved it.

    could be the distributor is loose.
    could be the advance springs are broken, or fell off.
    could be the distributor gear is going away.
    could be the timing chain/gears have a problem
    could be your timing light sux.

    Even a bit more obscure, but a couple of months ago I was checking out an MSD distributor that was going into a turbo engine I was rebuilding. There was a bunch of play in it, even though it was set up to be locked out. Turned out the locating pin was breaking free and required welding to correct.

    Timing was bouncing +- 10 on my locked out msd deal. Ditched the gear drive and put a decent double roller on it and does not move at all.

    What are you using for a timing light? I have a digital snap on timing light and usually have to advance the timing on the gun, +1 or 2 degrees for it to read right. Then just subtract the degrees you add.

    The light is a Sears inductive with no wheel. The pick up in the distributor is pretty rusty. Is it OK to clean it or should it be replaced? Thanks for all the responses. I will check into it this weekend.
