Tillotson updraft JR-1 carb RE: applicatons

Bolt centers are 2-3/8", throat is 1-1/2" What might this fit also a piece on the bottom is missing (what ?)

Tried a google? There are two lists out there with applications.

Then again, I have one here, a JR2A and I don't think either list showed anything with a JR designation.

I was told post a photo, so you might want to try that, otherwise good luck, no one apparently has any old carb books or manuals with that info in it.

If you look closer ot it, it is a model JR1A. This would fit a Graham Paige 610. We ran one of these originally (We have since upgraded to the 2A, for more performance). I am guessing it would fit others makes of a similar size. (Think Chrysler 50, etc)

Thanks I was curious as it wasn't for my Willys Knight or Nash it looked most like the one on the Ferguson tractor I use.

The Tillotson JR series was aftermarket only; there were no original applications.

In general, these units sold new for less than a repair kit for the original carburetors; so one may judge the quality of these units accordingly.
