If unless the throttle bushings were shot, and sucking air, and it had the solid metal float needle, more than likely, all it needed was a good cleaning. Any of these will cause fuel to keep flowing into the carb. I would have to guess when you took it apart, you've either bent the float some putting it back together, improperly set the adjustment, or, the the float axle ( pin that the float hinges on) possibly slid sideways, binding the float in a lower position. Hopefully someone can shed some light on my issue(s)!! Of course I could not find a listing for a TSX864 or a listing for a suitable replacement. So I thought, ok, I will just replace the carb. nothing made any change in the way it ran. Instructions said 1 turn which I was at) in & out. I tried adjusting the idle adjusting needle (it was set at 2 turns out. Started right up (idle) but in a couple seconds the same issue, too much fuel again. if the main nozzle seats upon the power jet.Īssembled everything but left off the air cleaner so I could view into the carb. I even broke a piece off of the top of the jet trying to. This time I noticed the power jet, located under the main nozzle. No external adjustments other than the above 2 items. Replaced the Needle & seat & idle adjusting needle. Pulled the carb and adjusted the floats to 1/4' from the gasket surface. This lead me to believe I have too much fuel flowing somewhere. Pulled the air cleaner assy and noticed some fuel was running out of the mouth of the carb (air filter side) when the motor would quit. Then started sputtering like the choke was on (it was not). Regasketed the carb and sediment bowl (marvel schebler TSX864 77Y) and reassambled with fresh gas. Pulled the fuel & air system (tank, lines, sediment bowl, carb and air box) and gave it a through cleaning. It was up to me to bring her out of its deep sleep. It has been 10 or so years since it last ran. Figured I would get it running & sell it, since it is not needed on the 'plantation' anymore. Never had to twist a wrench on it until 2 days ago. I have a McCormick Farmall 140 (ser # 63353 JHC) that has been in our family since new.
