Edelbrock Carbs!

[skink4president]

Just put a new Edelbrock Performer #1400 w/electric choke on my K5 350/350. Had an older edelbrock w/ manual choke on it before. Now I've got a low end bog. Timing is good (10 BTDC). I think it may be related to the electric choke although the problem still seems to happen when warmed up and the choke is fully open at operating temp.

Any ideas??? (other than, "take it off and put on a Holley!")

Is bolting the new carb to the engine the only thing you have done? Are the carburater idle mixture screws adjusted properly?

Check vacuum advance, vacuum leaks, idle adj and main jetting.

try this

there is a second hole adjustment on the acclerator pump try it after you check the other posts. hope this helps .

Yeah. I just bolted it up to the new intake. According to Edelbrock they come "pre-adjusted" for either economy or performance. I' ve fooled with the choke to some extent but that's about it. Honestly, this is my first square-bore. I've made adjustments on Q-jets and Holleys before but never one of these. Hell, I haven't even figured out how to adjust the idle yet!

you could have got a electric choke kit for yours cheeper.

you sir are in BIG trouble if you cant figure out how to adjust idle on an AFB, but have messed with Holleys and QJets.

Use a vacuum gauge and adjust the idle mixture.
Also Edelbrock carbs are crap for wheeling. I talk from experience. Cant climb a molehill without sputtering and dieing. Then a bee-atch to restart. Im running a Barry Grant Speed Demon now. Why? Because its what I had. I got the thing to stall on a bumpy 2 track. Then trying to stop and steer with the motor dead was fun. Get a Q-Jet. Or at least a Holly truck avenger.

I've had good luck offroading my edlebrock, but I used their offroad needle kit and adjusted per instructions. I also run an electric fuel pump. I have stalled, but only on the steepest of hills. I will be installing a TBI system in the next couple of months, to fix the slight stalling I had.
