carburator service manual

[CELSESSER]

Hi,

Does anyone out there have SM-2024 "Carburators for JD tractors and engines" ?
I am going to be rebuilding a TSX 641 and would like to know things like proper drill sizes for cleaning passages and tuning procedures.
It's on a 420 engine that was swaped into the 440 ICD.

Thanks,
Chuck
