Does anyone know where I can find snap on tools for carburetors? I have a few Holley 94's and the jets require a special tool. You can buy a special tool made by Holley, but it is flimsy to say the least. The Snap On tool is stamped TMC-38A. I just don't know of any places that might have them. Tried eBay several times over a long time with no luck. :(

Well its not listed on Snap-on's website so I think you may be stuck with a continuous ebay search, or if you can find a Snap-On dealer that will check around with other dealers to see if one can be found.

Are you sure the part number is correct? TMC-38(no A suffix) comes back as:

TMC-38

Stromberg Discharge Jet socket

1945-1955

I'm pretty sure it's not the same for a Holley 94

That is not the Snap-on tool for Ford/Holley 94 jets, which has been out of production for a long time.
First, you can do the job with a normal screwdriver...best is a fairly large blade for tight fit in the jet slot with sides of blade ground down a tad to go through the access hole. Many smaller screwdrivers will also do the job, but with some slop in fit to the slot. Usually not a problem. Carb must have it top off, as a screwdriver can't carry the jet in and out.
The original tool is a socket whose business end is shaped like the current Holley tool (also replicated by Speedway), just better made...it is a long socket to reach from the access hole to the jet.
Actual driver is two nubbins on the shell of the socket, inner part of socket is a bullet nose that goes into the large opening in front of jet and grips it well enough (usually) that jet can be inserted and removed as well as rotated.
The current tools I mentioned do and look the same at the tip of a screwdriver, but are not as well shaped to slide into and grip an unseen jet.
Only way to get one is dumb luck at the fleamarket.
The tool shown above is just a screwdriver with a collar so top screws on a carb can be removed faster without slipping out of the slot...I doubt that it will even go through the access hole in a 94.

They are cool, and allow you to change jets with the lid on...perhaps with an occasional fumble...but for normal life, a screwdriver is fine. Unless you live in Denver and work in Death Valley, there isn't a whole lot of need for jet changing in your 94...

TMC36A is it...the FMC 38 is another goody, allowing the jet plugs on both Ford 94's and Stromberg EE's to be removed easily from multiple angles. It actually fits the curved slot, which cannot be said of any normal screwdriver.
The TMC 36 A is hard to see there...the middle piece between the screwdriver tabs is what slides into the jet at the front (not the metering hole) to grip it. It is just like the tip of the current Holley tool in design, but is a bit better finished and shaped.

(Another good design feature of the Snap-on tool...the shank of the tool where it passes through the access is just under the thread diameter, so it pilots there, helping get it to the center of the jet so it will engage...very useful because of course you can't see the jet, if top is still on the carb)

You are correct, Bruce. Got a little carried away. The correct Snap-On tool is TMC-38A. I believe tool TMC-36A is for the Chandler Grove carb. Still looking......

Tmc36A is the jet tool for all Ford 94's and their close relatives with the access ports at front...this includes Ford script ones, the early Chandler Grove version, those made by Holley without Ford script as replacements, etc. That's most Ford V8's 1938-55 and a bunch of later replacement and aftermarket versions.
The tool will also work on the much later 4150-4160 four barrels, but its length anf grip feature are not particularly needed fo the 4 barrels because the whole bowl comes off on them.
The 38 is not actually a jet tool, it is simply a specialized screwdriver that removes the big screws covering jet access on all 94 types and also on Ford type Strombergs...it is not really necessary but works better than any normal screwdriver.

You are correct once again, Bruce. The correct tool is TMC-36 or TMC-36A. Still looking for one.

i've got two, both SO, never knew what they were. one is larger than the other, I think one is 1/4" drive. I'll have to check the part #'s to see what they are, but the larger one looks like the pic, the smaller one is about 2/3 the diameter.

On that Ebay one...it is the right one for 94, but the inner part that grasps the recess in jet has been damaged...the two halves are collapsed together.
To various people posting in this...if you have spare Snap-on or other carb tools to unload after Ethan finds what he needs, I probably want them! I work on olde Ford carbs all the time, and of course I'm a carb too nut. Bruce

I have a bunch of old carburetor tools including a new looking Snap-on TMC-36 discussed in this thread. Most are Snap-on or Blackhawk with a few Carter or unidentifiable. Is there anyone out there who might be interested in acquiring these?
