Basic carburetor kit fits John Deere tractors gas model 50, 520, 530 using Marvel Schebler two barrel carburetors model DLTX- 75,and 86 This JD33 kit contains all carb gaskets for the center bowl part of the carb, float valve with hardened stainless steel needle tip or the rubber tipped viton needle for the fuel valve, throttle shaft, bronze throttle shaft bushings, and the shaft that the float pivots on. The mounting gaskets to the intake manifold and to the air cleaner intake pipe are not included. Also includes instruction sheet with recommended float level settings and starting off settings for the idle and load adjusting needles. This fits JD carb number AB4794R. Please let me know if you prefer the viton rubber tip needle or the hardened stainless steel needle for the float valve. If you do not specify you will get which ever one I happen pick up first.

Get that carb cleaned out before next season so it goes right the first time. We recommend that you shut the gas off and run the carb bowl dry with todays corrosive gasoline. If you let the gas sit in the carburetor and come back a month or two later they can gum up and mess the carb up. Drain 'em or run'em dry and they won't give you trouble.


We have piston rings, decals, gasket sets and other parts for the John Deere and other tractors like IHC, Case, Massey Harris, Oliver, Minneapolis Moline, Avery, Ford. Ferguson, and Caterpillar  at ringspacers.
