Hey guys
When running a locked out distributor, would you still Time it with rpm’s over 3500 ? Someone told me I could set it at idle which is like 1800 . Doesn’t sound right to me .

If there is no advance, you can time it at 100rpm or 10,000. should be the same, theoretically.

If you have a computer controlling timing with a locked out, that's different

idle which is like 1800

Why that high?


In theory, there is no difference between theory and practice. In practice, there is.

I guess my thinking was that the requirement for advance would increase as rpm increases, at least to a point

If you have a locked out distributor and everything is perfect, you could set it at idle. BUT I always rev it up and check it again because a little slop in the distributor drive gear, ignition boxes may retard timing a higher RPM's etc. So just to be sure to rev it up and verify.

Set it at idle. Bring the RPM up to verify if you like, Should stay the same if there aren't a bunch of worn out parts in it. It will still move around some with a stock type set up. Lots of parts involved between the crank shaft and the distributor cap. Put a crank trigger on it and it will be rock steady.


If the results don't match the theory, change the theory.

This, and especially with a crank trigger.
