I was out running my 9N today snowblowing 18" of wet snow. As I was coming up my driveway it started running rough, the rpms kept dropping then coming back. When I got to the top of the driveway the rpms went to maximum and stayed there. The throttle lever had no effect on rpms, the engine stayed at max rpm. The governor has been acting intermittently sluggish lately as well but the tractor has been usable up until this point.
I checked the governor spring, it was loose so I took it off and adjusted it until it was snug but with no preload per the FO-4 manual. I started it back up and the rpms were screaming so I decided to put the tractor back in its parking spot. When I engaged the pto to lift the snowblower the rpms dropped but the governor kept hunting and the rpms were all over the place. The throttle lever still had no effect on rpms.
What else can I do to troubleshoot this? I'm not very familiar with governors, is it time for a rebuild?
Thanks
