Denny,

It's a Speed Demon 1402010VE. The specs are on this page.

I'll check the vacuum at idle in gear tommorrow . . . er . . . later this morning.

Sallee Chevrolet (now Gilbert Chevy) recommended the Demon 750 for my ZZ430 clone, although the Barry Grant website recommended their 650. In any case, I have the 750, and I should be able to make it work.

I'm also going to check the power valve tomorrow.

Pat,

It seems to idle OK with the butterflies set per the Demon book. Both butterflies are set so all that is showing underneath is a small square, so both are slightly cracked. I don't seem to have much trouble with idle. It idles at about 700 with a slight lope. It doesn't seem to load up at stoplights. I don't need to blip it to clear it out.

I've also got a little hesitation when I hit the throttle hard, but I need to fix this lean problem before I solve that one.

I did get a pop or two when I first started it up, so maybe I trashed the power valve. It feels a bit rich everywhere - not just at idle.

Thanks for responding, guys. I'll let you know about the vacuum later.
