Okay i just installed a better glow plug gasket and it's still doing what it was doing before.... And closer analyzed it, let me clarify... When the motor starts and gets to operating temp, as soon as the enging starts to get warm (water starts to boil off slowly) It dies and has very little compression like a worn motor. As soon as it cools down, it has plenty of compression like normal, start it up, rock solid idle, drive it around for a minute or two to warm it up bring it in, and it stalls and wont start back up again no matter what, as soon as it cools off it starts on the first pull and has lots of compression, forget removing and reinstalling the glow plug i was wrong, the plug is tight and sealing, as soon as the motor heats up, it wont start and has little compression, it only has like 5 tanks on it, it's been blowing smoke the whole time and hasnt over heated but it should have been running it a little richer during break in, i wasnt hard on it and it didnt run too lean, it just should have been richer, i am ready to send it back to OS....anyone got any ideas, i double checked head bolts, backplate bolts, carb, pipe, everything, as soon as it heats up i lose compression, when it cools I have compression
