Idle / acceleration issues
Yeah, I said to hell with it. Set total timing to 34*, went inside and ordered a Quick Fuel Slayer 750 last night. Thanks for your help guys!- bigmanisme

Idle / acceleration issues
Rich, I put it back to tdc #1. Redid the wires, checked the cap and rotor again and started fresh. Then did all of the timing / tuning. I found out tonight that the truck had been sitting for about a year. Previous owner said he started it "once in a while". I am now beginning to think I need to...- bigmanisme

Idle / acceleration issues
Roughly how many turns out of the idle / air screw should be normal? I have them out almost 6 turns. Is this normal? If I lean it out anymore than that it does the popping through the exhaust.- bigmanisme

Idle / acceleration issues
Bumped inital timing to 10* BTDC. It would only advance out to 30*. Switched to manifold vacuum and it idled better but ran worse. Switched back to timed vacuum and it idled a little rougher than the manifold vacuum but ran really well except it still has that off idle stumble. Took out on the...- bigmanisme

Idle / acceleration issues
No vacuum leaks anywhere. It was running ok without the regulator, come to find out the feed hose was coming apart on the inside so full flow was not getting to the carb. Fuel pressure is now at just over 5psi. Engine is stock as far as I know (previous owner wasn't too helpful).- bigmanisme

Whoever had the truck before me was running the stock 12psi pumps to the carb without a regulator. I ran new lines to a bypass regulator. After this is when this all started.- bigmanisme

Idle / acceleration issues
In the morning I will switch to manifold vacuum and bump timing to 8* and let you know how that works. Should I fatten up the idle mixture a little when I bump up the timing? Thanks for your help guys!- bigmanisme

Idle / acceleration issues
No on the damper slippage and sticking valve. I thought lean as well, so I fattened up the Idle / Air mixture with an additional 3/4 turn out and the idle cleaned up as far as the popping goes. Deceleration cleaned up quite a bit as well. Does seem a little undertimed upon take off. A little bit...- bigmanisme

I don't know what shape the carb is in since it was on the truck when I got it. I have everything to go through it so is that a viable solution to my problem?- bigmanisme

I have also checked Cap/rotor/wires for damage and they are in great shape.- bigmanisme

Idle / acceleration issues
I have an 1989 R3500 with a 1993 454 that has been converted with an Edelbrock 1411 750 carb. It just started popping randomly through the exhaust and deceleration. Gently take off from a stop and it sputters as if going to die. When I gas it a little more it catches and takes off. I have the...- bigmanisme
