Canada built used Robertson screw heads.

Do we know what engine is involved?

Not sure, but 0.004 clearance is plenty especially since the cam is turning 1/2 speed of the crank.

Since the clearance was not too tight it was an oiling problem.

An old way used to decarbon engines is to use your hose to heavy mist water into the carburetor only enough to not stall and let it stall or turn off and leave it overnight. Start it the next day. Do this carefully as to not hydrolock the engine while it is running.

Looks like a shot in downtown Culver City. My Grandmothers house just a few blocks south by the studios.

Do an internet search for "the Filling Station" in Lebanon Oregon, they should be able to help you

See that car?

It sounds as if there is blockage in the valving if the fluid needs to be that thin.

Try a NAPA store.

Jack oil works well.

If it has grease in it you can add light oil to thin it.

Just mask it. Why take a chance on damaging the block?

Gunmetal VS Battleship Grey!

Buy new at NAPA.

It looks to have "fun" potential. At least it has good proportions.

Nice project, don't pay too much. It will need a bit of work unless you plan to get it reliable and drive as is.

Your original can be rebuilt if not broken.

Check out a choke return spring for a model T Ford as they are similar.

I guess to start, if the answer isn't readily available, would be to measure the linings that are on the car, if any. The thickness should be the closest next 1 to 3 available sizes depending on how worn they look. In the '20s the increments were in the 32nds I believe.

Mid 20s, yes.

Check on EBay, or a spring shop.

If it is defective it should be still under replacement warrantee.

It was all the money printed and given out so freely during the "pandemic"
