Hermit - - I was suspicious of the valve timing last summer. The book said that on #1 cylinder, the exhaust valve should close just before TDC, and the intake open just past TDC. My tractor proved to be running 10-15 degrees late on all valve actions. The book also said that the starting crank pin in the nose of the crank shaft should be horizontal at TDC. It is 10-15 degrees off in the same direction also. Last summer, I moved the cam shaft timing gear 3 teeth to get the valve timing in line to the book. Problem wasn't apparently better or worse. Thoughts ? ? ? Pete
