The car idles fine. That's not an issue. The reason I'm thinking about it is 1) I like simplicity on my cars 2) Locked timing will allow me to run a crank trigger. I love the precision of crank triggers. I cringe when I see timing flutter at WOT. Every car I've had has done a little bit of that. Even just a degree or two bothers me!
If you shimmed the dist shaft you wouldnt
see any flutter
I have a collar on the shaft that fits tight up against the drive gear. Is that the play you're talking about controlling? I've never shimmed a shaft before
I think Mr Pbody is talking about shimming the distributor itself. Some of the stuff I've seen had .080-.090 slop in the distributor.
On the dyno with a customer supplied MSD that was wacky. It had .100 clearance.
Shimmed it to where it had about .010 and it was golden.
