Well, I have narrowed down the problem to the Marvel Schebler TSX428 bowl. I literally rebuilt the carb replacing one part at a time and trying on the tractor hoping to pin point the issue. Nothing helped with the only runs on choke issue until I got the idea of putting the carb from his super early Ford 2000 with the same carb on it. With just a brief peak to make sure it was clean put the other carb on and runs great, no choke. Decided to put the Jubilee's top half of carb on the 2000's bowl...runs great, no choke. Put the 2000's top half of carb on Jubilee's bowl, only runs on choke. Put the Jubilee's top half of carb back on it own bowl, only runs on choke. Now that bowl has been cleaned many times and visually can't see any reason for it not to work properly, new gaskets make no difference. A bit baffling but there's an issue with it. I do alot of carbs and been thinking about an ultrasonic cleaner, may have to finally pony up for it. Anyway, here's a pic of the carb choke plate with the flapper positioned in the carb on the 2000. If I installed the Jubilee's wrong someone prior to my dad did this one. Anyway, I didn't want to leave a thread unresolved even though it's kind of still not 100% complete. I at least know it's not fuel supply, timing, spark, or some other issue outside of the original bowl. I am now on to the next problem with the Jubilee....the lift.
