New crank handle shaft assembly fitted, so I can turn the motor over. This tractor has not run for many many years. I have poured a good dose of a diesel/engine oil mix in each cylinder. Removed the rocker cover to oil the rockers and valves and found black mess everywhere and a very strong smell of kerosene. Time to strip the motor and get the rebuild out of the way? The valves are not stuck. The liquid is my diesel/engine oil mix.
