Had a real bad oil leak and had a friend perform the repairs, he replaced the crank seal and the case gasket. Finally got time to mow and noticed that when I push the throttle lever to "high" the engine is running faster than it used to, seems like 1/4 throttle is about the right RPM. When I engage the deck to mow the engine speed drops quite low and even if I push the throttle all the way up to high the blades do not seem to spin as fast as they should. If I disengage the deck with the throttle on high the engine suddenly starts to over rev and i have to adjust the throttle back down. I was wondering if there was an adjustment or something with the governor that I could double check instead of taking the mower back to him. Thanks for the advice!
Hi, basically the bottom case will have to come off the motor again as your friend has failed to correctly position the governor gear against the governor arm, sorry Phil.
Testimonial: "Alright I was afraid that it would have to come apart again, thank you! "

YOU MAY HAVE A BENT BLADE OR EXESSEIVE BUILD UP UNDER THE DECK
