Allisgrandson Posted June 4, 2014 Posted June 4, 2014 I have bunged up the nozzle threads on the carb lower trying to remove the nozzle. I was able to finally remove the nozzle using a left-hand drill bit, but the treads are a little flat still. Does anyone know what the thread count and type is so that I can get a bolt to put in there to clean up the threads? Thanks, Brian
Brettw Posted June 4, 2014 Posted June 4, 2014 What carb, what engine? I think anyone who can help you will need this info, at a minimum.
briggsetc Posted June 4, 2014 Posted June 4, 2014 Brian, What engine ?? If it is a Briggs with the Medium Flo-Jet carb those threads are 5/16" x 32. Briggs sells a kit # 19245 for around 11.00, probably more now, with both taps for the small and medium flojet. Special size, 1/4" x 32 and 5/16" x 32. Ever get up to the Potsdam,Canton area? I have the tap set. Hey .. good excuse to come up to our show June 14 -15. See slpowermuseum.com Gary
Allisgrandson Posted June 4, 2014 Author Posted June 4, 2014 Sorry guys, I know I'm supposed to put that in! You guys don't know my tractors by now? The are off of a Briggs 10/12 HP 243431 from a B10. Quite a few variations. I'm working on the 4 bolt carbs with the short/removable air intake stack
Allisgrandson Posted June 6, 2014 Author Posted June 6, 2014 Briggsect, thanks for the info. I ordered them yesterday. They look like the parts I need. Brian
briggsetc Posted June 21, 2014 Posted June 21, 2014 Little late here but FYI... You need a 7/32 drill for the 1/4" jet in the small flojet and a 9/32 drill for the medium flojet. It will drill most of brass out and leave the threads before it gets near the nozzle seat. Then you push out the nozzle piece and clean the threads, works slick. Gary
