I solved most of the 107's problems today
Did some wrenching on the ol' K241 today in the 107, fixed a bunch of stuff. I know it's Christmas Eve but why the heck not?
 So I pulled the valve cover off. Valve clearances were a bit too tight. Exhaust was like .009, and intake was probably .003 or something else absurd. Got those adjusted back to the proper measurements, .018 on the exhaust and .009 on the intake. When putting it all back together I noticed that my reed valve was not functioning properly. I'm not sure if it's supposed to be, but the valve is sprung slightly in one direction. It was on there backwards, and it did not seal the 2 holes in the plate properly. You could see that it was at some time installed correctly as there were wear marks on both sides of the valve. I installed it properly and now it seals properly. Also replaced the fiber filter thingy because it was pretty small. Overall I'd say it was a pretty good day

Sounds like a dandy day, all days spent wrenching on Cubs are good days.
Even days just sitting and staring at em just pondering are good days. Ken

So today I decided to bite the bullet and adjust the hydro linkage. Drove her into the barn (running much better after adjusting the valves a couple days ago) and pulled the fenders. What I found I did not expect. The "damper spring plate" (as the manual calls it, makes up the outer part of the trunnion and holds the springs vertically) had about a half inch of play on it and combined with the normal wearing in the trunnion, the mechanism barely even worked at all.
IMG_20201226_125630.jpg IMG_20201226_125710.jpg Fortunately I had the same piece from the old shredded hydro. Simple enough, swap the worn one with the good one. However this did require splitting the tractor. No big deal, easily done, but not so easily in the freezing cold. So pulled the hydro, removed the speed control cam, then the damper spring plate, swapped in the one from the old hydro, put it back together, perfect. Almost no play at all. IMG_20201226_125741.jpg Then to tackle the trunnion wear, I used a temporary fix that I saw on here a while back. Took a thin piece of steel, cut it to fit in the slot, and bent it around with pliers. Worked perfect. Once all together, went to adjust the hydro creep, only to discover that there was no creep at all. Everything had been caused by the slop in the damper plate. That was a nice surprise. Put it all back together, took it out for a spin. Hydro control is much nicer and much more responsive. IMG_20201226_163429.jpg IMG_20201226_163444.jpg IMG_20201226_125723.jpg This leaves a couple things I still need to do: Figure out how to loosen tension on the control lever so that it moves a bit easier, and most importantly, figure out how to get the lever to sit on the shaft without so much play. The latter being top priority because the shear amount of play in the lever prevents the tractor from reaching full speed. Basically another great day wrenchin' on a Cub

It is behind the battery. It may just need some lube...

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.
MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
