351c starting & driving issues
#11
Quick fuel “brawler” carb for under 400 bucks. Works almost perfect out of the box.

I’ve quit rebuilding old carbs unless numbers matching. The new ones are far better. The brawler has 4 corner idle, 2 metering blocks, adjustable air bleeds, electric choke, adjustable secondary spring. It’s really a nice piece.

I just did a 351W for a friend. I rebuilt the old Holley. It worked fine. He couldn’t grasp the manual choke concept. Put a brawler on and the car is better. I had a slight off idle stumble that was cured with raising the idle an going a little richer on the idle.

A bog off idle at a traffic light is usually idle and mixture. The accelerator pump system shouldn’t be doing much.

I've already ordered a 600cfm Classic Holley with manual choke. I'm fine with manual and based on the reviews it's pretty reliable for street. The only thing is the non-adjustable floats. I'd only use the car for street/daily and the guys at Holley told that 600cfm is pretty much enough. I already have an MSD pro billet distributor, new wires etc and we'll install it on Monday so we can see how it'll perform.

"A bog off idle at a traffic light is usually idle and mixture. The accelerator pump system shouldn’t be doing much."  Danoh1  I respectfully disagree with this statement. 

 The whole purpose of the accelerator pump circuit is to provide additional fuel to accelerate from idle.  If you try to adjust that out with the idle mixture you will be running too rich and load up at idle.  If he were dying when just idling in gear I would agree that the idle settings were the problem, but when he says he can pay close attention and get it to keep running off idle, I feel that is a classic accelerator pump symptom.
