First time posting. I've got a Bobcat 722 (Ford 1.6L Pinto-style engine with Zenith carb) which seems to be running too rich. The plugs come out black and sooty, sometimes there is gas overflow when cranking the engine, and it stalls and dies whenever it encounters the least load. After it dies, I have to cut off the fuel and crank for about 40 seconds to get it restarted, during which time the exhaust smells like raw gas, which is why I think it's flooding. I flushed the gas tank and it's got fresh fuel, and a new high-capacity fuel filter with water trap, a new fuel pump, a new fuel pressure regulator set to the minimum 3.5 psi listed in the manual, new carb floats set a bit lower than listed in the manual, a new carb kit with new fuel inlet needle valve, and the carb is clean and there is no blockage in the bowl vent. It also has new spark plugs and new electronic ignition, timed spot-on. I'm running out of ideas for things to try. Anyone else ever run into this problem? I think this could be a nice little loader if I could just get the engine running good. Thanks, Nick
