Carburetor Tool

[Don Cavey]

I see this thing on fleaBay all of the time. I have not been able to find it in the -20 or -34 manual. Does anyone know what you do with it on the carburetor?

Thanks Guys...

If you drop the 00 after the 5120, then this is a part number like the 34 parts manual lists...so, if I read it correctly, the number is: 5120-168-2282
(could be 2202 on the end)

If that number is right, the parts book shows: WRENCH, CARBURETOR MAIN JET

And that makes perfect sense...

So, a fancy too for removing or installing the main jet... If you don't have a straight blade screwdriver . I have worked on Holley carburetors for many years and for sure, the 1920 on our trucks is not something special or all that much different than the 4150/4160 4 bbl.

Thanks for the answer!

No sweat.

If you are looking at part numbers on tags, I dont know why it is but it often is, they like to put the numbers in the 4 digit-2 digit-3 digit-4 digit format on the part or the parts tag or bag...the books though never have the 2 digit part...just the 4 digit-3 digit-4 digit style.


Sometimes the last 4 digit part...say it is 2300, may be abbreviated as 23...not that common though.

Thanks! That is helpful. I often like to buy those "Special Tools" when they are selling for next to nothing. Just nice to have "Stuff". It is a guy thing I guess...

Actually, when you've had as many carburetors in your hands as it seems I have over the years, you can appreciate a special tool for jets when you see just how badly well-intentioned mechanics can butcher soft brass objects.

Most jets in any carburetor are not a flat blade screwdriver fitment. They actually are cut at a bit of an angle on the sides of the slot and sometimes the bottom of the slot is angled as well. That is done for flow characteristics of the particular jet in question. That's why I am always quick to tell people who drill out jets or run a wire through them that it isn't a hole, its a jet. They are a metering device. That is also why I am very careful of aftermarket jets. Not all of them are created equally.

Nice tool and it should be in any toolbox of an M715 mechanic.
