I'm wondering if something is missing. When I removed the gov. housing, all I had inside were the gear, shaft, weights and (for lack of the proper term) a thrust bearing and small "fork" which is welded to the throttle arm. (the one across the front of the motor) The only spring in the system attaches the gov. arm to the throttle arm outside of the housing. Are there any springs that are supposed to be on the inside of this housing?
My problem is this, when mowing or even going up a hill in 2nd or 3rd, the governor doesn't advance the throttle. It just idles down and eventually dies. Any ideas?
Perhaps related, but I can barely pull my 5' BMB rotary through mild fescue/prairie/assorted small weeds, etc. (To put it in perspective, I had been able to mow it with my old 12hp Massey lawn mower.) Should an old B be able to handle a 5' brush hog or is this too much mower for the tractor?
