carb rebuild options

[meathead333]

just got a few question on my options...

are there more than one rebuild kit brand, any reccomendations?

if i were to have a pro rebuild the carb, would they do anything special to it that i couldnt do with a kit?

what tool/supplies, besides the kit would i need?

is there a "how-to" site or instructional book with good pics anyone would reccomend?

thanks

What carb are you talking about

 

[meathead333]

maybe i asked my questions a bit early....would this step by step be a good source to follow:
http://www.advanceautoparts.com/english/youcan/html/pht/pht20020301cr.html#

it says it for 1957-69 Motorcraft 2100-D two-barrel carburetor rebuild. even though i am not sure which year my carb is, would it be the same for my 2100(see pic below)?

Over the years I've rebuilt my 2bbl Motorcraft 3 times. Twice I used Advanced Auto as my source for the kit, this last time I got it at Car Quest. The Car Quest kit seemed more complete, I had to buy a couple extra things with the others ( got in a shoutin' match w/ the guy at the counter over that, but that's another story. ) No special tools needed, just a couple of screwdrivers and I used a 1/4 in. drive socket set.

Here's a book if your doing a Qjet that might be of help, it's suppose to be "invaluable" : "Rochester Caburetors" by Doug Roe, published by HPBooks. Its ISDN number is 0-89586-301-4 . I'm sure there's others out there for other carbs.

It's a fairly easy rebuild on the 2bbl, I'm not sure on the others, just pay attention when you're taking it apart. The only problem I had was not setting the float right once, ran like crap until I figured that one out.

Very easy carbs to rebuild i've done mine that i had on my 302. All the info you need should come in the kit along with the float measuring guage. My last kit was and actual motorcraft kit from ford but that was purchased about 9 years ago so i'm not sure if thay are still available. Basic tools are all you need and about an hour or two worth of time.

Not sure on the quality of different kits as I've never had any problems with any of the kits I've used cant remember who made any of them though. Every kit I've gotten has come with instructions and are pretty easy to follow but about all you need is the float level specs and choke setting specs the 2100 is probably the simplest carb to work on. I wouldnt sweat it.
The pros if you want to call them that really dont do anything different. There are a few that will set them up exactly for your engine but if they dont have your engine to test it on its a shot in the dark. Why pay someone 3 times the money it costs for you to do it yourself. After you've done it you will be able to fix it if it ever needs it again.

rebuilding it is pretty straight forward. but you really should have the right tools to tune it correctly. like a vacuum gauge, and a dwell meter. jeepster knows alot more than me about this. pony carbs is supposed to actually modify the 2100's to make them better. you cant do that with a rebuild kit.

my plan is to find a carb on ebay and rebuild it so if i mess up and take me longer than expected, its no biggie. theres quite a few 2100's on ebay, however, i'm kinda lost in the numbers. alot of them have #123, #108 and #121 in the description too. where would i find info on what carb i need?

 

[broncnaz]

Thenumber is usually stamped or cast on the side of the carb. Not sure how true this is but the info I dug up was this #108 is 450 cfm, #114 520 cfm, and #121 575. didnt find a #123 but I didnt look that hard.
I would just hit a local junk yard they should have plenty of them for way cheap as few people want them and they came on lots of vehicles jeep, AMC, along with fords. Should be able to pick one up for $20 or less.

ok, rookie question...whats 520 cfm mean? could i throw any of these on my engine? or do i need a specifc one?

rebuild time

since this sound like your frist one to try and rebuild ..i kind of like your ideal of getting one elsewhere to rebuild .so you'll still have yours to fall back on ..
1st off what does yours do that make you want to rebuild it ..
2nd rebuilding cant fix some problems ..like worn shaft on the butterflys
that is what the rebuild carb shops are "supposed" to be able to do ..
3rd you really need some carb cleaner ...not just a spray ...one to soak it in this stuff is expensive about 75.00 for a 3 to 5 gallon bucket course you could clean 50 carbs in one bucket but you only got one to clean ...they do make one gallons of it and after you take the 2100 apart it's rather small pieces ..possible you could get buy with one gallon ..berryman makes this stuff ...it' kind of yellow and stinks ..so get outside not in the house....
4th B W D .borg warner makes kit ..std hygrade..made good kit if there could be found anymore ..and motorcraft if good ...get a new float i liked the brass one best ..should be enough instruction in the kits...
5th even if i bought one off of something at a wrecking yard or ebay i'd look it over real good ...might even try to put it on before i rebuilt it so i'd know if it had any problems before i put the kit in it ...
6th be careful when outting one on that hasnt ran in a while ..or the one you rebuid...they can catch fire from float stuck and such ...
so be outside again not in the house garage about once a year i hear of some good old boy burning his house down from working on his pet project inside......
hope this will help ..i know it long ...but 1st one can have ghost in them

thanks for the info...

yeah, i think you have some very good points. im thinking it might be better to just get a new or remanufactured one. i know my wife would sh*t a brick if i rebuilt it inside my apt. maybe ill get one of the remanufactured holleys from summit or something and then down the road rebuild my current carb when i have the space and time to teach myself.

Just DO IT!

Just do it! Read the article from Advanced Auto and the one Mikey posted. You're not rebuilding the space shuttle, just a 2bbl carb. There's not that much to it. Take it apart and lay it out on a table piece by piece. Use a camera if you have to and photograph your dis-assembly. If you run into any problems, there's alot of guys here that can help. And then when you're done, you can say "I did it" and you'll know one more thing about your Bronco.

Rebuild

Hey I Didn't Mean To Stop You From Rebuilding Your ..just Wanted To Give You Some Spots To Look Out For ...i Think The Price For Rebuilds Is Way More Than They Are Worth But I've Built 100's Thur The Years ...
I Used To Own A Parts House ..we Sold Them And We Rebuilt Them ...
There Are Problems With Both ...
Go For It ....

I second the just do it response there is very little to mess up in these carbs. Other than dropping the carb and breaking it I dont think you will have any problems.
