Operating or storing the engine at greater than a 15 degree angle 4. Inoperative crankcase breather 5. Crankcase air leak 6. Blown head gasket 7. Worn cylinder and/or rings 8.

whats wrong when engine turn to a certain point but mower will not start,oil gas mixture in exhaust how do i fix problem

Asked by: c12ing
This could be due to a carburetor blockage or a stuck carburetor float needle and seat, the needle and seat is worn, or a problematic fuel solenoid (if equipped). You will want to drain the fuel and replace with fresh fuel. Next clean the carburetor. Here is a link on how to clean the carb:

How do I change the starter on my 42707 model engine?

when my mower gets hot and I shut it off, to wash out the mower deck, it won't restart until it cools off. The starter grinds but it just won't start, no matter if I choke it or not.
