Carburator

Finally think i have my Edelbrock 1406 figured out. After lots of tinkering and frustration she is done. My problem was after she got hot and sat, she was very difficult to start. I put on a 1/2" spacer and adjusted the floats on the carburetor. Just got back from a cruise and she starts every time.

Re: Carburator

I've got to adjust the floats on mine as it stalls when I make right or left turns.

What kind of spacer did you use? I have a phenolic and it worked fine but it was a little pricey IIRC.

Re: Carburator

Mine stalls when I turn left, I have a 1407 (750) that's too big so I just plan to replace it. Should I plan to add a spacer? I have a performer RPM intake. (Mostly stock 350 with a mild cam)

Re: Carburator

Where did you set your choke to? Mine seems to start ok, but accelerating is an issue. I think its choking itself out.

Re: Carburator

I'm having the same issue with accelerating, my 72 cheyenne feels like it's going to stall and die on me when I try to floor it. I took my truck to have it checked out at a shop they said it might be the camshaft but I've had others say it may be the carb settings.

Re: Carburator

On my first 71 it would stall/die when making turns or sudden stops - I didn't mess with the float but just raised the idle rpm with the screw on the front.

Not sure if that was correct to do but it did solve the problem.

Re: Carburator

I rebuilt my carter AFB (basically the same as the edelbrock) and it idles great and runs great. I thought I adjusted the floats correctly but through reading past posts suspect I must be off a little. I'll try the floats and it doesn't work I'll adjust the idle. I just really like how it is idling right now.

Re: Carburator

I have an edelbrock 650 on my truck, it does idle a little rough but it starts stalling but it doesn't die when I floor it, when making turns or stopping. I'll try raising the idle rpm and see if that works, thanks for the suggestion.

Re: Carburator

I added a wood/phenolic spacer. I also had to re jet and rod the carburetor. You guys with the accelerator problem, I had the same problem. You can adjust the accelerator pump and it will get rid of the hesitation problem.
