So I put in Langs Kingston L4 float chamber, mixing chamber and flange gasket in. I have the felt one and probably the float valve seat left over. See the picture? I think one of these gaskets was incidentally in the envelope. I don't know where these go and do I care?
The mixing chamber and flange gaskets where so far gone on my carb it was clear that's why the thing was leaking.
The thick felt piece is for the fuel supply line--it's what was originally used, not a compression sleeve. one of the others might be a spare gasket for the float seat to help adjust the float level.
Does the felt piece go into he body of the carb where the fuel line attaches?
No, it fits inside the fuel line but.
Inside the fuel line compression nut, the fuel line through the small hole.
What does the fuel line compression nut look like?
Like this. The felt or neoprene packing fits onto the fuel line after the nut, then the nut is tightened onto the carburetor fitting, compressing the packing and making a seal.
Oops! Didn't put it on. Thanks! -- IV
The other 2 are bowl nut gaskets the l-4 had two size nuts to hold the bowl on, Bob
How to smush all that felt into the nut? I tried it and a bunch hangs out. I don't know how to get it onto the threads?
Needle valve seat has a hairline crack and is leaking. What to do?
Ignacio, I'm probly WAY too late since you found a cracked valve seat but on the felt seal issue; do I see a brass ferrule/compression fitting already on the fuel line hiding inside the nut in that pic?
Dumb question perhaps. Is it the removable brass seat that has the crack?
Royce sure presents an easy method to fix that carb. :-)

I soak/saturate my felts, when used, with motor oil prior to installing.
I pulled about 1/3rd of the felt off and it went in ok. Looks like I have bigger problems with the cracked needle valve seat.
