checked the oil and it was WAY over full
I decided to crank it and CAUTIOUSLY watch it
oil immediately starts blowing every where
I drained over 3 gal. of oil and gas out of the oil pan
So now we know you DID start and run the motor if even for only a few seconds.
Gas will not lube parts. In fact it washes the lube (oil) off the parts. With no lube you are running the motor dry metal scraping on dry metal.
When you cranked the motor the oil pump started working as it should and drove the gas oil mixture threw out the entire motor.
Now that you are about to beat your head on a wall thinking you just ruin a good motor I will add............
Stop worrying. You only ran it for a few seconds. At most you took a month off the life of the motor.
On the other hand learn from this. If ever you find something wrong (oil way over full) ask first before you try running the motor. If you had run it for a while; say 30 min to a hour; you would be buying a new motor for your tractor right now.
