[wbs]

hello-does anyone know drill bit size for tillotson main jet? i read all old posts for the nominal sizes but they all covered zenith but none addressed tillotson. incidently, the size for zenith is #65. thanks

The Tillotson main jet id is 0.112, the small holes on the side of the main jet are 0.030.
The suppliers sell a book on Tillotson. Search this site for Mr. Texas he has a website with pictures on the Tillotsons he has repaired.

thank you- i'm kind of amazed that anyone would know the answer to that question. ive read that orifices are very important but are only 19% true to specs.

Who in the WORLD calculated that 19% of jets were not TRUE to specs??? Someone is full of B.S.!!!!

B.S. must stand for bit sizes, and that's how they calculate the jets sizes. LOL
