Well, i finally got my 302 started tonight, it was funny though i couldnt figure out why it wouldn't stay running, then i remembered that there was only 3 gallons of fuel in it, so it porbably wasn't getting fuel, lol fixed that and threw 7 more gallons at it, started right up. With the straight headers it sounded awesome, i was really close to having to change my pants:icon_twisted:, lol

but i have two questions,

one i'm pretty sure that the electric choke isn't working, as when it was running, the engine was cold and the choke was loose, i could rotate it without any resistance, and there was power going to it and it had a good ground. Is it bad?

two once the engine is reved it drops back down in rpms and wants to cut out, but if i just start it up and don't rev it, it'll stay running, what could be the prob?

it has a holley 4160 or 4150 which ever one has only 1 metering plate.

thanks,
Jon
 
4160 has one metering plate.

the choke might need to be adjusted.

did you set the timing with a light, and adjust the idle mixture?
 
yea the choke is working now, it was turned to far and i didnt notice.

but i'm still having the reving issue, i installed a tach for the moment till i get a good one, and it says when i start it up and its just sitting there running, that it is running at 2500 rpm, now when i rev it a touch and try to drop it down in rpms to like 1500 it tries to cut out. wtf could this be? i set the idle screws back to a basic setting, 1.5 turns out, and it had like 20 in/hg of vacuum i think is what the gauge said, which is also in the green zone of the gauge which says normal engine idle. But i can't figure it out.

there is also a good bit of bluish smoke coming out from the breathers, i was guessing that that was just because it's a fresh engine but i didn't think it should be coming out of the breathers so much.

help me please.

thanks Jon
