I FOLLOWED THE BREAK IN PROCEDURE LIKE I WAS SUPPOSED TO. THE GLOW PLUG WAS STILL INTACT, THE WIRE HAD NOT BLOWN APART IN THE CYLINDER HEAD. I CHECKED THE CYLINDER WALLS AND COULDNT SEE ANYTHING OUT OF THE ORDINARY. NO SCRATCHES, NO PITTING. THE TOP OF THE PISTON WAS GOOD AND DARK THOUGH. THE FILINGS WERE SMALL AND ALL OVER THE PISTON HEAD. IS THERE ANYTHING BETWEEN THE CARB AND THE PISTON HEAD THAT COULD SHRED LIKE THAT? THE TRUCK WAS POINTED STRAIGHT UP WHEN IT WAS HUNG UP AND STARTED TO REV UP. COULD THE FUEL/LUBRRICANT BEEN DENIED TO ANY PARTS THAT NEED IT? THIS IS MY FIRST NITRO AND BOY IS IT A LEARNING EXPERIENCE.
