Woodchuck · Jun 11, 2010

Stumbles and dies. Anyone know what model it is so I can get a rebuild kit?

Looks like a M/S carb to me Bart.

This YT site under TRACTOR PARTS.
Carburetor Kit, Basic - For Zenith 13876 carburetor on 2N, 9N, 8N. (Part No: BK44V)

P.S. Plane Bart's picture looks like a M/S type, not a Zenith.

Was the Zenith commonly used on a 9N or was this an after market change?

The Zenith carbs were "after market, but work very well on the "N" series Ford tractors.
Here is a list of all the OEM Marvel/Schebler TSX carbs, that were used on
"N" series tractors....OEM:

The best carb out of this bunch is the TSX241B, but all TSX carbs were/are used!!!

Before you rebuild the carb, are you sure that the carb is your problem?
Check the spark first. If that"s good (FAT, BLUISH-WHITE, the color of lightning)and the timing is correct, then check the fuel delivery to the carb to make sure that it is good.

Make sure the carb adjustments are correct and check for air leaks around the fuel metering part of the carb(throttle shaft, intake manifold to carb conection, cracks or rust spots in the intake manifold, intake manifold to block gasket, etc). If these are good, then consider rebuilding the carb.

It"s best to do some analysis and find the root cause of your problem rather than to jump to a onclusion and start throwing parts at the problem.

I stand corrected then Thanks

I have a buddy that runs one of those on a TO 35. He got tired of dinking with the MS that was on it and hes pretty mechanical. It may just need the main jet opened up or a general clean up. I see no reason for pulling it if on a worker. They aren't cast iron and has much less potential for rust problems.

Pulled the carb and completely dismanteled it. Cleaned everything with carb cleaner. Blew everything out. Reassembled and put it on the 2N. It runs better than ever. Put the MS on the 9N and it's better but I think it still has spark issues.
