My stump grinder was running great, I replaced or worked on the teeth and now it won‘t start?
Easy fix, when you had the nose of your grinder up in the air for extended time the oil from the oil pan has flooded the piston cylinder and your cylinder is full of oil. This creates compression and you cant turn the engine over.
Remove the spark plug
Remove both oil fill caps, this allows air flow
Let it sit for a day over night is best
Replace the oil caps
Give it a shot of starting fluid in the spark plug hole
Replace the spark plug
Now start your engine. 9 times out of 10 you’re in business. It will smoke until all the oil burns off, this process can be timely. You may even see oil from the muffler until it burns off.
