  • Rebuilding Marvel Schebler TSX33 carb
  • Hi All, I am in the process of rebuilding my carb off my ‘41 9N. I have been having a heck of a time getting the
    small jets out. They are corroded in there. I cleaned them out with a torch cleaner wire, and blew them out with compressed air. Decided to leave them in. I have a question regarding the float. Mine looks damaged where the pontoons are smashed in on both sides. I find it a bit odd. Also, I cannot seem to find a new drain plug for the bottom of the bowl. Mine was corroded in there so badly, I had to heat it up to get the plug out, destroying the plug. I guess I can make a trip to the hardware store for a fine thread plug that size. I find it strange no rebuild kits that are offered has these two items ( float and plug ) included. Has anyone else been on this journey?

    I have read on some forums not to but one of those Amazon offered, 30 buck carbs. They’re Chinese made and junk… I want to keep my original in that case. I’d welcome any input Thank you.

  • I finished rebuilding my TSX33. I replace everything except for the small jets. They were corroded in there and I was afraid I would booger up the jets trying harder to get them out. I adjusted the carb, but did not run as good as it used to. Pretty disappointed. I have a original TSX33 carb. Getting some surging at low idle and will die if I idle it too low.

  • The plug is a 1/8" pipe thread 27 threads per inch. A brass plug fitting will do it.

  • You can buy a new float from Just 8Ns or from Yesterdays Tractors.

  • Floats come in some kits with prices to match. You should be ahead of the game to purchase it separately. No guarantees on that though. As for the plug, you are correct. A trip to the hardware store is in order.
