Tillotson JR5A Carburetor Main Jet replacement part, or replacement carb?

[norm cushing]

Hi All,

 

Can anybody point me in the direction of how to obtain a "Main Jet" for a Tillotson JR5A carburetor, or a replacement carb?

 

I am working to get a 1929 Chevrolet International AC 1-1/2 ton truck up and running. It has the Tillotson on it rather than an the original OEM Carter, but the Tillotson carburetor needs to be overhauled as the idle adjustment does not function. The "main jet" is stuck in place and cannot be removed at this time and thus it may have to be destroyed to get it removed, thus a replacement may be required.

 

Your good guidance, suggestions, advice, words of wisdom would be very helpful.

 

Respectfully, Norm
