390.. new starter, solenoid, dizzy, I dont run headers, 4v edelbrock. I really believe since i ran those grounds it is fine. the only thing is that the carb is flooding out... I just drove it around the block and would idle fine except for when aggresive on brakes...

I finally got a tach... When idling it is consistently at 900 rpm. When in gear (reverse) and foot down of brake it got a consistent 600 rpm. When ebrake was on and no foot on brake it got 700 rpm... What rpm should everything be at.

I belive that i have to rebuild my carb. Even though it has low miles it would only eliminate another problem. I believe i am also going to run another ground from my engine to my fire way. I currently have a ground from frame to engine. and firewall to engine (when i did this one it started better).. I had to use a wire from a starter (only thing they had in) would that work? Im going to run my old starter wire to firewall, i dont think it would hurt it.

I think it would start but it acts like its flooded. Wish me luck guys and if that doesnt work, i dont know what will.

There is a series of problem that have occured if you want to see them check out the thread "will vac leak cause carb backfire" in the 67-72 forum.

 

I really don't know where you are going but the idle should be around 600, when in park. If you are having trouble starting, what is your timing eset at? Advanced too far will cause problems. If the carb worked good before, you have other issues I think.

I've found in my past experience that the FE seems to run at it's best when she's a little on the "hard to start" side. (Almost as if the battery is bought dead)

When their cold, they've always fired right up with a touch of the key.(hell, sometimes I reach for the key and before my hand gets there, they start up!) However, when their on the warmed up and I go to start 'em, the battery sounds about dead. And that's when I know their tuned up just right!

i got sand in my carb when sandblasting and tried to get everything out. I think that some got in the accelerator pump and stayed there... making it bad. My timing is set at 12 btdc, its not off my a tooth, i checked. Before it was hard to have the starter turn cuz of unefficient ground. Now it turns better but not like when cold, heck i doubt it ever will. I have confidence though that at the rate the starter is turning now, it can start my truck. However my carb floods everytime.

I have a pretty big cam so it cant idle at 600 or else it will die. I can try and make a smaller rpm though. Maybe play with it until it is running better somewhere between 600-900 rpm.

Before my problem was a ground. I have a huge ground wire. The only problem was that it was mounted to the frame. I made another ground wire from the engine to the firewall, and then it turned over way better.

My dad is an electrician and he told me that if i mounted a ground wire from the firewall to the frame then the frame will have a better ground. So im going to try and do that so i can get better use out of that 2 or 4 gauge wire i used for a ground.
