Do you have parts #1 and #9 in place?

Yes I do have those in place
This morning it was more or less 80° and I decided to drag my long stone driveway which I do at a low speed the drag maybe weighs 120 pounds and is 5 foot wide. I kept the engine at just above and idle and it ran for quite some time when it began to sputter and die I opened the hood and noticed the oil fill cap has three vent holes and you could see oily smoke pouring from those three small holes. While the engine was running I removed that And there is a lot of pressure coming from inside the valve cover but it made the engine come back to life

I am thinking this one needs to be torn down and rebuilt unless it is a valve issue

I've not seen a Command with three vent holes in the fill cap.

As stated above, the fuel pump works off crank case pulses. As the pistons go up/down, pressure rises and falls in the crankcase and pulses the diaphragm in the pump. I don't see how the pump could work with a vented fill cap or even the crank case breather.

I could be all wet but don't think so.

Well it makes no sense that there is a picture of a gas pump on the cap
But there is definitely pressure under the cap

I've never seen a cap like that one. Kohler may have moved the reed valve breather to the cap?

Maybe someone else can help?

I would expect to see a cap like this on that engine.

Probably should have the correct Oil Cap.

That is not a Kohler oil fill cap.

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.
