Edelbrock Reman Carb

Runs great right out of the box

and

Runs too rich out of the box

and

Runs too lean out of the box

to...... runs like crap.

Bottom line, there's not a single carb anyone can sell that will run perfectly balanced as far as A/F ratio for every engine right out of the box.

So we're going to hear all 3 at one time or another........ depends on engine size/displacement, cam overlap, pumping effeciency, velocity moving through, etc. It's just not possible to have a "one size fits all" carb.

For one thing - there's a difference in jetting between the manual choke and the automatic choke versions of the SAME carb. Now once that choke is open, auto or manual choke has NO impact on the mixture to the engine....... so right  there is a difference. Mine is a manual converted to automatic choke. But how can Edelbrock say what my engine needs, especially based on the CHOKE? They can't. So what they do is put a good average in thoe box - then sell a lot of the jetting kits............. so you can make it right. There's a lot of "runs great" cars out there running too rich or too lean and they would run better if a sniffer was up the pipe and it was properly tuned.

 

My take on reman carbs? They suck. I quit using them back in about 1978 or so. In fact, our shop wouldn't install them. (I've toured facilities that do carb remanufacturing and trust me - what goes in isn't what comes out of most............ the parts are dumped into big baskets and cleaned with little attention to jetting, metering rods, etc.)

I've seen them so bad there was obvious stuff wrong - stuff a "intro to auto mechanics" studend should have caught. I've seen warped parts, plugged air bleeds, float settings WAAY out of whack, loose parts, bad gaskets, you name it.

 

That doesn't mean I'm against "carb rebuilding" - just means either I want to be the one doing it, or it's being done by someone I trust. No remans, though. None.

When a major shop stops using them, there's something to it, IMO. Yeah, you'll here the "oh, why not, I've had great luck" stories, yes - they exist. But over several years using many dozens of carbs, we found the odds were against you.

 

Check for fuel pressure that's too high - I think Edelbrock might want a limit of like 5psi, is it?

Check for float level, or leaking floats. Check for plugged air bleeds. This is a common thing and allows siphoning in some carbs. Floats might also be not moving freely, touching the sides or other issues.

On mine, I could hear the fuel boiling after the engine warmed up, so I  know what one issue was, but that's been solved.....
