Ok, anyone on here ever rebuild one of these?

I have rebuilt the Holley 2100 and the 2150 (high altitude) among other carbs.

The choice is a good one. The carb is essentially 1/2 of a double pumper.

You can get the rebuild kit from any Holley dealer, but I advise you to get a Holley manual.

What engine is it for?

BTW I did my 8007 and the job is not particularly difficult but is exacting

IH pickup (345ci... 5.6L)
I was thinking of rebuilding it, but then I found a place that can do it for $140. So.... I will probably have $50 in parts can cleaners. $90 labor doesn't seem too bad.
engine runs great at high speed, but idles rough and the gas tanks were all gunked up, so I am guessing the carb is gunked up also. I am going to pull the bowl off and clean out the float as it seems to be sticking a little and spitting gas out the vent tube some times (unless I knock on the bowl).

That spitting out the tube is a sure sign. You may have a sticking needle valve. That is a safety issue for you. If it sticks open you can easily get an engine fire.

yup, and currently I am running fuel from a wine bottle I have to pull and clean/seal the tanks... yes, there are two tanks.

$150 sounds fair, considering a rebuild kit is $45, and assuming they know what they're doing. I was at a carb shop in Westland about a month ago, and they wanted $400 to rebuild/restore a carb I've done Holley 4150's/4160's, and they're very similar, and pretty easy. Only hard part is getting the parts clean.

Yeah, this is what the company does...Other places were about $190. He also talks about the proper chemicals etc. Sounds like he knows his stuff. I have to shop the carb, but that is no biggie. Plus, he will warranty it.

Heh, why that carb ? Because you have it ?

How so ?
jaskispyder, how much is a rebuild kit ? $30.00 I would guess. $50.00 in carb cleaner is excessive and $90.00 in labor, ... I would pass. How much is a rebuilt replacement from the parts store ? Weigh your options. A Holley is not hard to rebuild.

Let me clarify.. the rebuild kit is $40-50, plus the cleaner, brushes, rags, etc. Now there are extra parts that may not be in the standard kit and I have to add a few bucks for those (based on others who rebuilt these carbs for their IH truck).

Rebuilt replacement is $300 on up. New is $500+ and it is generic... which means jetting and such.

I want to keep the stock carb as it is recommended and basically plug/play. I don't want to have to adapt or adjust another carb to fit. Heck, if I was going to do that I could add TBI injection

I've had both the Holley 2 barrel and the Holley 4 barrel to work on. Essentially the venturi sizes are different on the 2 barrel, but the float bowl is interchangable, the power valve, the accellerator pump and diaphram, etc. The 2 barrel has no secondary system and it doesn't have the extra float bowl, but the primary system, accellerator pump system, and the float/jet system is identical.

I looked at the same situation and ended up buying a rebuild myself. $90 in labour is not too far off shop time price for an hour. Some shops do $60 and I doubt you can do a proper clean, soak, teardown, reassemble and adjust in under an hour. If a local guy uses fresh cleaner fluid in his part bath, it can hit $50. I'd say if the shop is reliable, it is the cheaper way to go. Given it is just a 2 barrel that is likely the reason for the price.

Yeah, I've rebuilt a bunch of those. I have a matching pair in my garage right now. I was going to custom fabricate an intake for my 2.8 that would take 2 of those HW2100 series carbs, but sold the motor and went with a 4.9. They are awesome carbs. I may even have the rebuild kits if you need one.

Cool. But I think the kit may be different... maybe not. There is a 2100 carb, but I believe it is a slightly different design.

Here it is:

Yes, that is an older model side hung

There is a guy in town that rebuilds them for $100 plus what ever the kit cost.
He blasts the outside so I will be able to paint when I get them back.

Totally worth it to me and he stands by his work. Plus I walk through a speed shop to get to him and they have the rebuild kits sitting on the shelf.

FYI, pulled the bowl off and there was a lot of gunk in there. Old gas, as screen was clean. I cleaned everything and put it back together. It ran better, until fuel came out the vent tube. Found that the oring around the float shutoff was bad and letting gas past that. I replaced it with another (for testing) and that solved the extra fuel issue. So, it is getting better, but I still believe I need to rebuild the carb.

FYI, update. It looks like the rebuild kit is $30, plus I would need a few extra parts (generic parts in kit need to be swapped out) and can cleaning solution.
I am looking at about:
$30 kit
$10 power valve
$20 for cleaning solution
$10 misc items

$70 total which is half of the cost of having an experienced person rebuild/test the carb.

Hmm

I used to rebuild carbs for friends after I did my first few for myself. Holley and Edelbrock are the easiest I have ever done; they are so much easier than Quadrajets.

I don’t do it much anymore because of my short term memory loss except on my own vehicles. The guy who taught me said the hardest part was making the outside look new, and most of that you can avoid. It is the insides and float levels that are important.

I have rebuilt the edelbrock twice right on the engine of our yard plow truck, something I have done so many times I wasn’t worried about screwing it up because they are so simple.

Good luck and remember what I said.

Yeah, my concern is the cost vs result. It looks to be easy to rebuild, but gathering all the parts and the extra cost is an issue. Verses having someone just rebuild it.

Holley and Edelbrock carbs are simple to rebuild compared to Quadrajets. If you can remember the instructions in the rebuild kit fairly easily. If by chance you forget something just start all over. I have only ever had one carb I couldn’t rebuild to better than new and that was a quadrajet, also a 30 year old one at that.

Just replace the things you need to and make dam sure the float level is right on the money, oh ya make sure the floats still float. That got me once.
I think it takes about an hour to do it right so go for it, unless you are like me now and can’t remember crap because of my stroke. But that’s me.

ordered the kit recommended by Holley... 3-396. It is obsolete, but I found one. It is a marine kit... interesting.

Well, having no luck, as the 3-396 was soaked in oil and the guy wouldn't sell it.

I am looking at Walker rebuild kits. The problem is that the standard kits from Holley don't have the proper throttle body gasket. It looks like the Walker kit does. Dang Holley.
