    Default Schebler Air Valve Casting Part Needed

    On a ride this week my air valve adjusting shaft came apart. The only part I lost was the air valve spring retainer nut. I have a Model H 3/4". Any leads would be appreciated. Thanks.

    NL967A, is it this nut?



    If so it is an east part to make if you have a lathe. If not then there must be someone near to you who could make one for you.

    Hi John
    Yes this is the nut. If someone has one they would be willing to sell let me know otherwise I'll get one made.

    I'll look. I probably have an extra. Were you using the cotter pin?

    I am fairly certain it's a 10-32 thread.

    I am curious how this could be lost on a ride without getting into the engine?

    Sorry to get back into this late Folks,

    But there were some that were #10-32tpi, but also some that were #10-40tpi.

    Try a common nut first, John!

    I agree! That nut and cotter pin would have gone straight down the hatch. That is the reason the motor company had a cotter pin there like other vulnerable areas. Bob L

    Folks,

    The carburetors were made by Schebler, not the 'MoCo', Indian, etc., and they did not use cotter keys.
    It was a peened brass pin (as was the throttle assembly), easily duplicated with filler rod.

    PS: I am reminded by my photo library that I have also encountered very early models that were soft-soldered, and not pinned at all.
    PPS: Apparently I have encountered oversize airvalve shafts as well, so anything is possible with a Schebler.
