Hello everyone I'm new to the forum and have a question concerning my MF50. I'm not sure of the year but anyhow it has the 4 cyl gas engine. The problem I'm having has been ongoing for a year or so now. The tractor will start and idle just fine and it runs great until you get it hot and in a good pull like pulling a 6' disc or 6' bush hog in heavy grass. Then it wants to spit and sputter until you mash the clutch and it'll clear up a little but still won't run very good. I have to hold the choke just to get it back to the barn. Then you let it sit a little while and it cranks up and runs like there was never a problem until you get it in a pull again. I just rebuilt the carb in hopes to fix it to no avail. The fuel tank is clean on the inside. I've also thought it could be vapor locking but I have new 1/4" rubber hose from the new sediment bowl to the carb. The points look good and are gapped to .022" New plugs and wires. Any help will be appreciated. I'm about ready to make a trip to the scrap yard.
