Locked out distributor advance question

Dave Muller · 05-12-2019, 09:34 AM

I recently locked out the advance in my distributor. I took the car out for testing with my backup engine last night and while the engine has some issues, the distributor worked out fine, and I had no trouble cranking when hot. But the timing did wander back and forth a couple of degrees, and when I put it in I could feel the rotor moving back and forth just a little.

I'm pulling the distributor out anyway to swap back to my good engine now and I'm thinking of putting a little tack weld between the plates to prevent any movement at all. There's no electronics in this, just the magnetic pickup. I don't think that would be bothered by one second of arc.

What do you guys think, good idea, bad idea? Any drawbacks other than the obvious increased difficulty in restoring centrifugal advance later on?
