Yesterday when I went to mess with it here's what I found...

After trying several times to set the points yet again I noticed that the trigger for the coil had somehow completely broke! The little fork that goes under the nut broke completely off! I have no clue how this happened. I did get the engine to run, but it ran violent. It must have broke at that point. See that machinist put the wires that to to the stator on the wrong freaking side. In noticed this after I had everything including the PTO and clutch installed so I just extended the wires 6-8". I ran them along the points wire and then made a loom with electrical tape so it would at least look like it belonged there. The wires are about 2" too long, but they're not in the way of anything so I left them. So really I don't know how it broke, but whatever...

At this point the battery was dead, so i decided to check the valves. Since the "t" mark is either non-existent, or too rusted to read, I put my finger over the spark plug hole to find the compression stroke. I then pulled the head off and used a dial indicator to find true TDC. The intake was set right at .010", but the exhaust valve was set way too tight. At this point the battery was still not charged, so this is where I left off.

I did manage to get the engine to start and run, but it only ran for 2-3 seconds then died. After that it wouldn't even attempt to start. I thought that maybe it was flooded so I took the plug out, cranked it a few times, and blew it out with compressed air... Still nothing. I probably should have left the points alone at that point but I didn't thinking I could tweak it a bit and get it to run.

At this point I'm 99.99999999% sure it has to be something other than timing. The plug is new and set at .035", the points are new Kholer points. The shaft is a new shaft. I thought maybe it wasn't staying set, but it is. Turning it over by hand I have compression, and the valves are set correct (well now they are). The carb is brand new and the only adjustment it has is for the idle set screw. It's getting fuel to the chamber, too... What can possibly be preventing this engine from running? Is it possible that the govenor is preventing it from starting? This is the only thing I can think of...

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.
