    Default Carburator repair

    Ok, not boat related...

    My father has a 1916 International truck. The carburator was leaking, it progressively got worse. He took the carburator to a guy in the area who fixes old engines. To make a long story short, it needs the float replaced, and one cannot be located. Talking to Dad, supposedly these were originally made out of Cork and coated with something of "varnish". I have not seen it, but I don't understand why one could not be fabricated fairly simply. My question is, what type of material and what type of coating?

    It's boat related for sure...If you have the original there's someone who can replicate it .....if it was made in 1916 from cork it wasn't made by a machine..any specialist vintage boat, car, motorcycle restorer will have been down this road before for sure. This is the place to get definite info certainly but the reply could be from Jayin Oz or Bigfella in the Mekong delta.
    keep checking your local restorers. honestly it shouldn't be a major problem. If you really draw a blank I'm in the land of cork. someone here can do it.
    'C'est la vie' say the old folks it goes to show you never can tell

    originally they were coated with shellac
    but modern fuel additives including ethanol dissolves shellac
    many restorers today paint the cork with superglue (cyanoacrylate)
    you should be able to find a brass float that will work as a retrofit, i'd look at the small su carb catologs, they will have a small place to rivet them onto the lever that the cork float was originally attached
    Simpler is better, except when complicated looks really cool.

    There are places that make replacement floats. I would post over on “Smokstak”. That entire site is antique engines. Might even ask over on “Oldmarineengine”.

    All the old Marvel Schebler carburetors used cork floats. Shellac was the original coating and is gasoline impervious but not alchohol - so no good with todays gas.
    I have made several cork replacements and even some for Amal's w/brass floats from balsa wood and cork both, coating them with West system (2 coats), so far so good maybe 20 years? I think the Balsa is easier to work, for the pivot I use a small brass tube available from hobby shops. Any tabs or needed protrusions can be easily soldered on to it. All the metal work was finished and fitted prior to epoxy coating.

    Try looking through Hemmings Motor News. That has long been called the "Bible" of old auto restoration. There will be ads for specific vehicle makes and ads for specific component services. There will be carby experts in there hawking their wares and services. I would be surprised if you cannot buy a float ready to install.

    I had a 1920 ish IH tractor with an unusual carburetor, not Marvel Schebler or Zenith, it was a brass sidedraft with an adjustable main jet, and circular float. I can't recall the name of it.
    Just curious, what manufacturer and configuration is your carburetor?

    (anything like this? note the cork float and hinge)

    Holley used to make side draft tractor carbs post WWI. They were cast out of ductile iron. In the 1950s. They even reintroduced replace carbs for these tractors, but they were cast from bronze. The original Holley foundry was on Jefferson in Detroit.

    I am familier with the early Holleys for Fords but only in iron, I always thought these bronze models were cast by IH.
    Do you think they made by Holley?

    (There is the IH logo on all the pieces)

    my dad probably would've known, he brokered and bought two old ih tractor plants and a foundry that served them, his shop walls had an amazing collection of engine and tractor parts overflowing from virtually everywhere

    Ensign is the name that I remember from old (really old) Cat and IH tractors. The models I fooled with were all fuel carbs, start on gasoline, run on kerosene
