Query: what do you call this tool? I need one

[Lawson Cox]

What do you call the design of the tool used to remove main jets in a Stromberg 97 carburetor. I think it is called a double D. Two capital D's back to back. The screws holding the top on a Trico motor have the same shape.

I need one for the Trico wiper motor, but don't want to sound too stupid when I call a tool guy to buy one. Anyone know the size for the Trico wiper motor screws?

I have one of those tools, but as the old saw goes, I can't find it. LOL

Thanks in advance.

I think this is what you mean (highlighted), clutch head type

[Lawson Cox]

Nope. Sides are straight, not wiggly like the clutch head. Thanks anyhow.

Hi Torque?

Take a piece of 3/16 brake line tube and squeeze it just a little--makes a perfect tool. Try it, you will like it!!!!!

Almost nearly, but not quite hardly. lol I may take Jerry up on his suggestion. The screws go into pot metal on the Trico motor, so minimal torque.

Used the half-assed pair of pliers on my Swiss Army knife on those things myself. I think a good set of fingernails will work in a pinch. But a bad case of corrosion may alter the equation . . .

The Bundy double-wrapped copper-plated steel tubing used originally for fuel and vacuum line squeezed lightly in a vise work just great, as indicated by Jerry. Put a 90 degree bend in it up the line to create a handle to provide some torque. I've used one for years.

Squeezed brake or copper tubing works or a small pr of mini vice grips works well too.Its NONE of the above pics.Its smaller than a jet tool but right its called a DD socket.There is a tool that snap-on sells DD and smaller but not sure if its the right size.Catch a SO truck and show him the screw it might fit. Its another carb tool. ken ct.

You can see a couple of those weird little awkward bolt heads in this photo of a vacuum wiper motor.

Hello I struggled with those special screws on the top of the trico motors . Tried small vise grips needle nose pliers. worked OK untill you get to the ones close to the raised part of the casting. recently I was frustrated after trying unsuccesfully to get these out. I took an old junk phillips screw driver. The smaller one. I cut off the phillips end off so just the shank was left. Clamped the shank in a vise,with the handle end down. Then I took my die grinder and cut a slot in the shank end. Then I took a Jewelers file and filed the slot untill it was a snug fit on the trico screw. Got all those screws out in about a minute! Amazing how easy a job becomes with the right tool. I made it myself and for cheap. Try it you'll like it.

[Lawson Cox]

Thanks for your input. I'll try flattening the piece of 3/16 tibomg as Jerry suggested.

Tools made for the job are very hard to find, harder than vintage jet wrenches. I have a double ended one that does both of the sizes Trico used over the years, but have never seen another in decades of scrounging.
There were several small double-D wrenches needed for many of the last carburetors detroit used in the early 1980s...these are getting scarce, too, now that even the last carbs have nearly vanished from the general population on the road.
A check on Amazon shows a variety of carb sets with several double-D's, one kit mentions " 2mm, 7mm, 10mm Double-D"....see if the things caliper near that.

Remember a Jessica Simpson ad a few years ago. She was in shorts and a little top and her line was, "I don't know what it is but I totally waaaant it."

This one if for shocks, so it's to big, but same ideal.

Have a machinist freind make a tool out a peice of drill rod for the jet removal tool.

For Stromberg jets: None finer than the tool Uncle Max makes. Worth every penny.

Yes, Chuck Chambers made them, but he is no longer with us. I have one he gave to me when he stopped by to visit us on a trip down south. Only problem is, I can't put my hands on it right now. Too big for the screws I am wanting to remove at this time.
