This message is a reply to an archived post by Britt J on March 06, 2012 at 17:57:07. The original subject was "8N governor problems".
I had the same EXACT problem with my 8N with a governor I bought from this site.I used the gov set screw to set my rev at 2200 and it resulted in virtually no throttle movement and two choices idle or runaway speed. What I found by unscrewing the stop screw all the way, taking the links off and running the engine with on hand on the carb butterfly and the other on the governor that in the distance that the governor arm traveled by the time it hit where my set screw was adjusted it was not far enough for the little fork inside the governor to hit the fly ball thrust washer. so the spring never loaded and the governor never worked even after all new linkages from the hand throttle all the way to the carb. SO... I figure in the new governor the fork inside that rides the flyball thrust washer is too short or the thrust washer is too thin. (that's my theory anyway and is much easier to understand with workshop pictures and disassembly of you governor) So how I fixed mine was with the engine running, linkages off, hand on the butterfly and hand on the governor long arm started the motor manually idled it and pulled the governor arm til i felt the resistance of the flyballs. After this I throttled the engine with my hand holding the governor long arm steady and I saw the short arm move toward the radiator that would have throttled the engine down. (all this was with the linakges off!! My hands doing the functions of the links to see how the governor acted!!!) SO I marked the position I found the long needed to be in to ride the balls when the throttle was moved and found that with my correct brand new link that pushed the carb open so I found the distance the link from gov to carb needed to be to have the carb closed with the long arm in that position and made a shorter rod. With my rod shortened a few pieces of an inch it made up for the extra distance the long arm had to go to hit the fly balls and presto the governor works like a champ!!! I just wished I knew if it was too short a fork or too thin a washer or what that is causing the problem I accidently threw my old governor away. sorry this was so long and hard to follow

Today's Featured Article - Search For Spares - by Anthony West (UK). Following on from the aquisition of the old Fordson F, I was very much in need of spares. As a novice though I didn't appreciate the fact that there were so many Fordson tractors made, that all the other makes seem rare by comparison. As far as I was aware a fordson was a fordson and it was only through trial an
