Slow to get here but the perfect part
Part must have gotten lost in the shuffle, had to inquire about status with email, 3 working days before part left your facilities. However all other aspects were great!

Diagnosed that fuel pump wasnt working. Carburetor was obsolete so no rebuild kit, so i bought a new one and installed it while I did the fuel pump and replaced the fuel lines and cleaned out the system. General tune up and tune. My father in laws cub cadet runs just like new, and sounds healthy again.

Lawnmower tractor would run while cold. As soon as it would warm up it would stop.
