Farmall H metal carb float valve - where to get

Old F-14 · Mar 9, 2018

I'm tired of pulling my hair out with these rubber-tipped float needle valves on my H. They work for awhile, then something in the gas makes them swell slightly where they don't seat well.

Don't try to sell me on the virtues of the rubber tipped ones. I've been through several and yes, the carb is clean as is the fuel tank.

Anybody have a source for a metal tipped (Original style) float needle valve?

Shut off the fuel at the sediment bowl, allow the engine to run out of gas and die. Float valve will not stick when it is open.

Sadly rustyfarmall has the right idea. I shut the gas off on everything I have and run the carb dry. I get so tired of people saying this new gas junk is trouble free. I have had nothing but trouble with older engines. The new ones seem to be more tolerant of junk gas. IMO

I have 2 Hs that never give trouble, and I never shut off the gas. On the other hand, my M will give trouble just setting overnight if I don't shut off the gas. E10 in all 3 tractors.

McDonald Carbuetor Parts has a tremendous amount of hard to find parts for IH and other carburetors. Never know, they just might have an old metal needle laying around. Their catalog of course shows the viton tipped needle.

Try Mark's carb & magneto at Rice Mn.

I'm sure I have several used all steel float valves out in the shop. Somewhere. Every single one of them has a groove worn into them, which is why they were replaced. The Viton tipped float valves do not develop that groove unless someone abuses them and tries to "set" them by hammering.

I have been shutting off the fuel and running the H until dry, the engine stops. I think that runs all the gas out and the float drops, and releases pressure on the plastic needle. Anyway, I have never h ad a problem with the thing.

Well, I solved it.

Tore apart my spare H carbs, and only one had the metal needle. But it had the wear line in it. Chucked it in drill press and carefully turned it till the wear line disappeared. Then carefully lapped it a few times with really fine Clover Compound.

Works great. Too bad only had one spare carb with the metal needle valve in it I could reface and re-use.
