??? - Removing fuel nozzle from M-S carburetor - ???

Posted by Alberta Mike on June 14, 2000 at 18:07:53 from (209.115.159.116):

I have a carb here, a Marvel Schebler TSX28 which is the same as most M-S carbs on medium-sized tractors from the 40's. I have a problem, namely fuel is coming out of the top (visible) gasket on the main brass fuel nozzle that threads (lower down) into the bowl half of the carb. I have learned from bad experience that getting this little beastie out is a major problem, probably because we always think it's turning and actually we find out too late that we are twisting it off (lower down where it threads into the casting) and all of a sudden the nozzle is in two parts, one in the socket and the other still in the carb. Here's a number of questions:

1. Any suggestions or tricks on getting the nozzle out without twisting it off?

2. Should fuel be up that far to the top gasket of the nozzle? I thought that middle portion under the top gasket is the start of an air chamber (with the lower threads sealing off the lowest part of the chamber where it sucks fuel up from the bottom).

3. If a guy does have one that is broken off, obviously it is in tight and in a very inaccessable location. How can I get out the broken brass stub down at the bottom? I've got a couple of those here that I'd like to fix up.

4. Where can I get the brass nozzles? I see where the MS carburetor kits do not have them with the kit. Everything else but the nozzle.

5. If a guy was to drill out the broken stub and rethread the casting, what size of thread do we have here?

Your answers to any of these questions would be greatly appreciated. Thanks

Mike
