68 383 with 750 carb. Runs rich
Hello
I’m just finally able to start driving a car I picked up before winter. Just back from mini tub. It’s a 383 auto eldelbrock torker manifod with a Holley 3310 750 vacuum secondaries. 391 rear gears 3000 stall. It’s start right away cold but it’s is running rich with fumes. It seems to drive okay though. I did adjust the air/fuel screws to highest vacuum (about 12 inches car was in park) using a vacuum gauge but no effect on richness. I should have checked timing first as I don’t know where I’m at. The big issue above running rich is after a ten minute drive shutting off and trying to restart 1 hr 30 mins later it cranks away but won’t start (has happened four times now). It does eventually start and runs great except richness.
When it didn’t start I did check spark and it was good. So I took apart the carb just now as I’m waiting for a rebuild kit. Is there a smoking gun I should look for inside? The jets were 72 and power valve stamped 6
although it appears they had two gaskets on it. Got to love the fuel line routing to but hey it’s a father son project.
Thanks
Greg
