Have you ever had something, and thought that it was right because you never knew any different? Well, I am overhauling a DLTX-10 from a 39' B, and have a question on the nozzle. When I take off the big nut and drop the bowl, just what should come out with the nut that was up in the stem? It seems I am missing the spring, and maybe even the nozzle. If the nozzle was in there, would I be able to push a wire or rod up from the bottom of the stem into the main bore? Right now there is just a brass tube in the stem that seems tightly pressed in. It has run in it's current state, but never that well. I do intend to clean and drill all the side passages. Like I said, since I never knew any different, this is a bit confusing. All help appreciated. Thanks guys, (and gals).

Cam, the springs job is to hold the brass nozzle up there in place, but I never took an old carb apart where the nozzle fell out under gravity. On my DLTX10 I drilled and tapped the nozzles inner lower bore with a 10/24 tap and used a long bolt and washers and screw to pull it out of there. But I eventually sent it to Robert Beaver who informed me that tolerance where the nozzle fits up in is important, cause if too tight, gas dont bleed out those tiny horizontal nozzle holes, and thats why the spring is supposed to be needed to hold the nozzle up in there in the first place. Also, remove all the brass drill plugs and use his extra long 40 and 53 drill bits to properly ream out all the teeny idle circuit passages and be sure the throttle shaft bushings are tight etc etc. Good Luck Ol John T

John T - Now it is starting to make sense. As long as I have had the B, the spring was never in there. I hope the nozzle wasn't tapped in to hold it. I'm making headway! Thanks.

Go to: Link which is their front web page, and then go to the "tractor school" part; then to the section on removing the nozzle. Basically, they tell how to get the stuck nozzle out - that's apparently your problem. I had to make a tool to pull mine out. Then I cleaned it up, drilled out all the various passageways with special size bits from Link By the way, roberts web site has probably even better information.

Yes Cam what you are seeing is the main nozzle. To remove it you need to tap some threads in the bottom of the main jet or venture as some call it. Then screw a screw into the main jet and pull it main jet out of the body. The spring you are looking for is in the main tube to hold the main nozzle in place. You can find a spring that will hold the main nozzle in place if you can not find the correct spring. Now comes the fun part, removing the small brass screws. Heat the body up with a small tourch around the screws and they will come out fairly easy. Do not break the slots off. if you do you need to drill them out and they are pricey from Deere and company. Use the correct size drill bits and open up each passage. One small hole on the idle circute is hard to see if it is clogged up but if the tractor does not idle good that is most of the time the culpret. It will be the next to the lowest brass screw on the main nozzle body. Start with a very small drill and enlarge the drills as you clean ont the passage, until you hit metal. Do not enlarge any of the holes or passages. If you do the Carb is dead.

Thanks, Used the heat trick on the drill plugs, and went 5 for 7. Drilled the last two. Still working on getting the main jet out
