Tuning a DZ 302

John (who wrote the article) runs his Z that way on pump gas - no issues.
As do many others.

I think you could have the advance come in sooner that that, btw.

You guys have me convinced. Ill hook it up and see how it performs.
These forums are very educational, don't know what we would do without them.
Thanks

after I had my distributor done about 12 years ago I never rehooked my vacuum advance with no issues. All advancement is in around 2,800.

Iv never had issues running vaccume advance unplugged. I find running with it off the engine runs cooler. The only down side is it takes a few extra minutes to get the car to &quot;warm up&quot; vaccume Advance builds heat and can cause pre detto if you run poor fuel with a true 11:1.

When my 1969 Z/28 was idling poorly and almost stalling at a stop sign or red light my mechanic, in addition to other things he did to the carb, made the vacuum advance inoperative. The car has run fine and no longer has the decreased idle or stalling at a stop.

I hooked up the vacuum advance. I had to turn the idle down because of the extra timing. It seems to run pretty good. I do have to shoot a little extra fuel in to get it to start.
