Back in January I gave our good friend Ken Updike from Carter & Gruenewald a call and ordered a new Governor spring (121709C1 Spring) as well as the 1/16 scale cub with snow plow. The spring and toy tractor arrived promptly. Tonight after supper there was still a good bit of daylight left now that the time has changed. The weather was mild so I decided to tackle replacing the governor spring tonight. I pulled out my trusty IH Service Manual and thought back on what I had seen while watching Gary Dotson take apart a Cub Governor at a Cub Fest then proceeded to remove the governor housing. As you can see from the pictures below the spring was the culprit as we suspected. I cleaned up the housing and did my best three handed man impression and finally got the new spring back on. I gave Bigdog a quick call just to make sure I had everything the way it was supposed to go before, I put it back together.
Everything went back together just like it was supposed to. I turned on the fuel, connected the battery, shook hands with the gear shift, set the choke, pulled the ignition switch and pulled the starter and she fired right up and had a full range of throttle. After she warmed up I took her for a short spin up the road and back through one of the housing developments. The new spring did the trick. I do believe that the governor is now more responsive and can feel a good bit more power now. Bonnie arrived home from class in time to watch me back it back into the barn and cleanup for the night.
