Hello All; My son and I are restoring my '64 f-100 that I have owned since '88. It has been parked since '02. It has a 2bbl carb on it but is not original. Current carb has an auto-choke that will not let the oil bath breather sit on properly. How can I find out what originally was on the truck. Rock auto has 2 carbs they say will fit, one has a hand throttle (does that mean choke?) and one style without. They are Autoline brand.

 

The 292 in 1964 was provided with an Autolite 2100 2bl with 1.02" Venturi, carb tagged C3TF, #48 jets and 7.5" power valve @ 0-5000 ft altitude

This is a small carb, but by 64 the Y blocks were detuned quite a bit. They work great. The 2100 with annular discharge booster cluster is one of the best carburetor designs ever made. Tuned my slick up and went from 9 to 17 mpg highway.

Welcome to FTE btw.

 

Thanks for the info Tedster9. If I'm unable to find one in a junk yard any suggestions on an after market brand to get or avoid? I have seen them from $75 to $400 on the internet.

 

Depends on what you guys want to do. Don't go too big, a smaller carb will run better. It's all about fuel atomization. Venturi size is what determines that.

Plus, who's gonna be paying for tires? ha ha

 

I want to go back t the original carb that came on it. Wouldn't that be a C4TF since it's a '64? What brand should I stick with?

 

Here ya go.

1964 FORD F-100 4.8L 292cid V8 Carburetor | RockAuto

That will get ya all fixed up.

 

Thanks; I saw those but wasn't 100% sure. My next question about those on Rock Auto, what they are calling hand throttle does that mean hand Choke?

 

Not a choke, some trucks had a separate hand throttle for locking the engine throttle and in turn engine RPM when driving things like a PTO. In that application they only had a manual choke.

You wont go wrong with an Autoline rebuild. They have been rebuilding carbs and distributors for 50 years now (Canadian company headquartered in Winnipeg, Man) all their remans are done in the US or Canada and they are one of, if not the best of the major rebuilders of carbs on the market.

 

Thanks for all your input, I think I will pass on the hand throttle version. I am sure I will have more questions as we get deeper into this project.

 

The 2100 is an excellent carburetor with a loyal following. The offroad rockcrawlers like them for example because the design allows for extreme angles without stalling. Not quite EFI but pretty close. Pre-64 examples use standard size Holley jets.

The carburetor manuals are available for download, Mikes Carburetors for example has them at their website in .pdf, 1964 Ford Truck Shop Manual is available in reprint form, or on CD can't recommend this enough. The specifications sections has all the data on what carburetor shipped with that truck, settings and adjustments. Not to mention the rest of the truck - brakes and steering, for example. The 2100 is super simple, but the baseline settings with any carb new or old need to be fine tuned.

Be sure to ask what size venturi before ordering, they may ship "whatever" size they have on hand. This translates into the CFM rating for the carb. 1.02" was stock, but they were available in 1.08" 1.14" 1.23" etc, and then may have some oddball mismatched booster cluster installed by now. This is the biggest problem with carburetor tuning. If the wrong carburetor is installed, people try all these contortions to try and get it to run right, jumping 10 jet sizes etc. The most important adjustment is to install the correct carburetor! The venturi size is stamped on the air horn of the carburetor.

Carburetor size depends a lot on what you're trying or want to do. Ford shipped all 1964 292 equipped trucks with a carburetor that flowed 245 CFM. Sounds way too small right? What the hell do Ford engineers know. And in some ways it is but these were trucks designed and intended to haul heavy loads. That's why I cautioned don't go too big on the carb. The CFM carburetor calculators are usually setup for 100% drag racing. A lot of parts choices are going to be completely different when the engine only ever sees wide open throttle. Down in the low RPMs where most people drive a smaller carb has crisp throttle response no bog or hesitation and smoother idle. And highway cruising at 50 to 60 it's right in the "sweet spot". Be sure to install dual exhaust and some Smithy's or Porters. Trust Me.

 

I dunno if we are allowed to do this, but I have one available I just pulled off my essentially stock 292 and a spare parts carb (no choke hardware on the parts carb) with spare sets of Holley jets if you are interested. It is an manual choke Autoline and only about 7 or 8 months old. Jetted for sea level now #50 IIRC. Spare carb is the one that came off the truck originally. Has a bad economizer valve but that should be a no-brainer to fix. Both should be the 1.02 venturi.



Should be pretty much bolt in and go. I'll let them go super cheap if interested. I upgraded mine to a 1960s Carter AFB.

Thanks!
