I'm going to be talking to a carburetor expert in a few days, and was hoping you all could give me some questions to ask him. He's a wizard with Webers, but also exceedingly knowledgeable about carbs and fuel delivery in general.

Fire away!

How to make hot restarts possible. My edelbrock has always been problematic in that area.

Why are you still screwing with carbs when FI is cheap, easy and waaaay more efficient?

That's what I would ask him.

or.... here's my other question. "So what's the ratio of black magic, voodoo and sheer luck required to make carbs work?"

How to make transient engine response faster? in other words, how do you tune out part throttle to full throttle bogs effectively.

Also.. +1 for why are we still screwing with these things.

man, so many haters. Although Swank Force may have a great question, as I imagine his answer would have something to do with their cost, reliability, and simplicity.

My question to the carb guru (pick any):

  • What's your most commonly seen amateur mistake (you know, when people come to you for help), what are the symptoms to look for, and how is it fixed?

  • If one wanted to "tune from home", using the minimum tools possible, how would you go about it?

  • Any advice for someone who wanted to run multiple carbs for the first time? I'm interested, but scared.

  • Any chance you'll be able to visit one of our readers "Hungary Bill" in Tacoma, WA? He wants a little help with his Rochester.

Good times

Carbs are still around for the same reason PASCAL programming is still around. There are old things still in service that use them, regardless of whether it would be wise to upgrade them So let's move on from that point.

I'm sure that I could just Google this one:

What is the advantage to running a side draft vs a down draft?

I would like to hear his thoughts on matching carb size (CFM's) to the engine it is being used on.

If you are a weber wizard, whats your opinion on a mikuni side drafts? Or who is the mikuni master?

Whats the best way to tune for an edlebrock 750 cfm, 383 sbc, 2800 pound road racing car with a true ram air and cold box set up? I keep asking cobra guys at car shows, but I dont think they can find the carb! Thanks

Serious question here:

Will enlarging the vacuum hole on my Keihin CV carb slides actually increase throttle response? What are the negative impacts of doing this? What else will this effect?

Here's one: A lot of parts store rebuilt carburetors seem to have terrible behavior out of the box - if you get one of those lemons, what can be done to fix it?

Geepers guys get off your high horses with the carb hate. They work well. And something like this is why we still mess with carbs.

It doesn't get much easier than bolting on a new Holley or Edelbrock, and both can be had new for under $400, then jetting it for your application.

I agree that EFI is preferred and more efficient, but I don't see it as easier or cheaper. If it were most of mine would be converted by now.

I now use a wideband to help dial in my carbs, which saves a lot of guess work

My question:

Are you seeing failures and/or corrosion due to ethanol, and if so, what can be done to prevent or minimize it.

OK, how about this one : a bank of side-draft carbs from a large motorcycle like a GSXR-1100, adapted to a 4 cyl car engine of 1.8 to 2.0 litters, good idea or bad idea? Suppose its a smallish car that splits its time between road and track use.

Now that carburetors are useless hulks with no purpose, what else can they be used for besides holding pencils?

Can they be used to aerate wine or in the case of individual setups... mix drinks? I need a novelty for my bar.
