Remove that nozzle But, please call me Meli...
    Many people have wondered how to remove the nozzle from the carburetor. It is usually pretty well STUCK in there. Please take the time to make this special tool and do the job RIGHT. Your tractor will APPRECIATE the effort, and YOU won't damage anything in the process. The tools described in the following paragraphs fit the nozzles in the John Deere Model A and Model B carburetors. For a bigger tractor like the Model G or Model 70, you would have to use a larger diameter treaded rod, for a smaller tractor, you may have to use an appropriately smaller rod.

Slide hammer for removing nozzle from carburetor

A Special Homemade Tool

    The "official" way to remove a stuck nozzle from a John Deere Model B carburetor is with a slide hammer. Here's what one looks like:

1. A piece of 3/16" rod, 8" or 9" long.
2. Thread the rod on the end... #10-24
3. One piece of scrap steel shaft, attached to the end of the rod.
4. Another piece with a hole through it, so it can slide. (movable weight)
5. The nozzle in question.

    To use it, first you thread the hole that goes up through the center of the nozzle. Use a #10-24 tap (this will NOT hurt the nozzle). Then you screw the slidehammer into the nozzle and bang the movable weight into the weight in the end of the shaft.


    Note the following changes to construct a slidehammer for a Model A carburetor:

1. A piece of 1/4" rod, 8" or 9" long.
2. Thread the rod on the end... 1/4-20
3. One piece of scrap steel shaft, attached to the end of the rod.
4. Another piece with a hole through it, so it can slide. (movable weight)
5. The nozzle in question.

    To use it, first you thread the hole that goes up through the center of the nozzle. Use a 1/4-20 tap (this will NOT hurt the nozzle). Then you screw the slidehammer into the nozzle and bang the movable weight into the weight in the end of the shaft.


     If the slidehammer doesn't jar the nozzle loose, you can help "push" it out by pushing a piece of hard wood or soft metal through the throat of the carb and tapping some wedges above it. Do NOT try to do it JUST with the wedges! Use this ONLY as a means of HELPING the slidehammer, if necessary.

    Once the nozzle is removed, scrape the opening clean so that it fits "loose". The only thing that holds it in during assembly is the spring! The nozzle should fall right out when you remove the bowl from the carburetor.
    You say there is NO spring holding the nozzle in your carburetor?? Well, SEE... The nozzle has been stuck for SO long that the spring wasn't even replaced when it rusted away! Your John Deere dealer can order one for you. It is part number R10078R. (It is the same part for the Model A and the Model B)
