Another part puzzle to solve, takes some thinking!

It looks like the washer that is used on the 1921-27 mufflers to help hold the rear shell on.

A washer from a windshield frame adjuster

I went out and looked at the original muffler that come off my 21. It is the style that the pipe goes thru and is the inner baffle. The washer on it is cupped, the outer edge presses on the rear cap. 1-1/4 in diameter, 3/8 hole, about 1/8 thick. The stud it mounts on is 5/16. The question does not say what material it is made from, but the windshield washers I have seen were brass with slots 90 degrees to each other.

Too big to be the muffler end washer, a HINT is given in the original ?.....that is two repairmen each found this washer taking two separate engines apart...read that carefully . BTY the washer is steel.

Keep on thinking....that thin tapered edge washer got into these engines somehow.

I would guess the remains of a valve.

From Bruce's book, page 564:

DEC 20 (1922) (Engine production records)
"Began using 3/8" washer at #4 manifold stud to keep
from bending hot air pipe."

Phil

That would be a regular washer, used to prevent the flaring of the ears on the early series of hot air pipe.

The crowned or domed- shaped washer in question is wafer-thin tapered to the edge, unlike any standard washer. .....

Another hint....that little washer is found on a supplied Ford part.


A standard washer helps to prevent this:

I'll stick by my observation. I've got several of those washers, and they were used on the muffler at the rear!

Larry

Agree that the little thin tapered to the edges domed shaped washer in question might look like in the sketch as a muffler end plate washer behind the nut holding the muffler together, but is not that washer.

Do you suppose a muffler end plate washer could be found inside an engine?

This puzzle is rather extremely difficult, as the author of these Questions, Murray Fahnestock didn't immediately know the answer.


And this little washer part was later deleted......

Maybe a button off of Steve Jelfs coveralls

Art, Steve isn't quite That old

Dan was there a puzzle #2?, cant find that one

It’s the washer that goes under the nuts on the outside of the firewall for ‘26-‘27 cowl mounted fuel tank straps.

Good call, Adam - I don't have any T's that new !

I'm going with Adams observation. Cowl Tank mounting strap washer. Replaced mine couple of years ago .
I suppose you could use it on the end of a muffler too.

The Reveal...here’s the mystery of the little thin washer.

Hint was attachments to intake manifold and what major supplier.

The carburetor and a major supplier was Kingston.

Seems the Kingston is famous for the flapper and that little washer was part of the flapper assembly.

Some owners from 1915 to 1919 had these troubles as the flapper assembly came apart in the Kingston L and L2. Later ones and the L4 used a revised flapper assembly to prevent this occurrence. So if you are experiencing poor running of your early L or L2 maybe the old style flapper assembly is the cause

And now for the next question: How many rebuilt Kingston carburetors get a new fiber washer on the flapper?
Answer: Not many
