I have a Kingston 5 ball carburetor on my 1910 T Model Ford Touring. I have just rebuilt the engine and don't want to damage it by the ingestion of any foreign material through the intake. Looking at the carburetor I see there is a thread on the inside diameter or the air intake. Q. Is this for a spark arrestor or an air filter, I have seen what I think is a spark arrestor it screws into the intake but its only about 4 inches tall but I've never seen a filter. The air intake is upright not angled.
Any information greatly appreciated.
It is a spark arrestor, but it could double as an air filter for any larger chunks of debris.
now all I have to do is find one!!
Might not be that hard to make one, may be a pump supply will have some screen, a welsh plug soldered on the top, a brass plumbing fitting may be the same thread? or slip it in with some adhesive of your choice.
I have a repro one, can't remember which vendor it came from. Lang's list a hot air pipe. Stan Howe would probably know who does the filter.
on the left is an original filter for a Kingston 5 ball, on the right is an old reproduction. Both are probably available if you look around.
Maybe you can use a cut-down fuel tank strainer from a Model A Ford?
You can find a brass tube with that oddball thread in the plumbing dept of a good hardware store. It is either 7/8 x 32 or 1 x 32. That would be a good start to making one.
My thanks to all for such great advice, I guess its back to the drawing board with a view to making one.
Many thanks to Kerry, Jem ,Kim, Stan and of course Ed in CA
