Rotor Cap Play normal?

Rusty's right on the money. That little window on the cap is for adjusting points dwell on a Chev.

Good looking distributor,,,,is the cap tight on that one ?
I’ve never heard of that brand,,,but it’s worth a try.
Hope it works good for you,,,,reliable service and smooth running .

Yes. Sure enough is tight on the new one. I really needed to go with a distributor that I can change curves easily as my engine will be getting at a minimum new cam and torque converter at some point. This dizzy is programmable from my phone or laptop. Small family business in Florida. They have a good reputation.
