I'M HAVING BIG TROUBLE WITH MY IH 444 TRACTOR WANTING TO DIE ON ME AFTER IT HEATS UP AND GETS UNDER A LOAD. IT WAS RUNNING JUST FINE AND THEN ONE DAY.......PLAAA! I'VE REPLACED THE POINTS AND CONDENSER AND ROTOR CAP, CLEANED OUT THE CARB. NOTHING, ADDED AN INLINE FUEL FILTER, REPLACED THE COIL, THEN REGAPPED THE POINTS. BUT IT JUST KEEPS GETTING WORSE IT ALSO WANTS TO BACK FIRE WHEN I TRY TO RESTART IT BUT IT WILL NOT RESTART UNTIL IT COOLS OFF COMPLETELY. ANY SUGGESTIONS? ONE STRANGE THING IS THAT I CAN HOLD ONTO THE COIL TO DISTRIBUTOR CAP WIRE WHILE IT IS RUNNING. EVERYONE SEEMS TO THINK I SHOULDN'T BE ABLE TO DO THAT WITHOUT GETTING ZAPPED. I'VE LOOKED AT ALL THE WIRES AND CAN'T FIND ANY SHORTS OR BREAKS. I'VE ALSO RUN A WIRE STRAIGHT FROM THE BATTERY TO THE POSITIVE SIDE OF THE COIL THAT DIDN'T HELP OR CHANGE ANYTHING EITHER. I'VE CHECKED FOR MOISTURE AND CRACKS IN THE CAP. IT WILL USUALLY RUN A GOOD STEADY HOUR BEFORE IT WANTS TO DIE. I'VE BEEN MESSING WITH THIS THING FOR WEEKS AND CAN'T TROUBLE SHOOT IT. I'M PRETTY SURE THAT I HAVE GOOD FUEL PRESSURE I'VE CHECKED THAT THE NEEDLE VALVE OPENS AND CLOSES AT INSTALLED POSITION, THE NEW FUEL FILTER IS CLEAR SO I CAN SEE THAT IT MADE IT TO WITHIN 3" OF THE CARB. THE TRACTOR HAS AN ELECTRIC FUEL PUMP AND IT'S STILL PUMPING GOOD.
