Plug is removed, connected to the boot and making connection to the block, I pull the cord or have another person pull it and you can see spark plain as day. Although I think its kind of weak compared to other tests I have seen. I haven't done a comparison to another plug yet that is on the weekend to do list.

John, that is honestly my next step and it won't take much its a tiny little engine. I don't see how timing can be off, with not having any valves in the engine. So, next is a complete tear down, which may take 30 mins to do to see if there are any signs, then I plan on a complete seal rebuild etc. After that I may just give up on the freebie, but all the signs are there that it should run just fine. Bore scope does not show any issues with scoring on the wall either. |

Do a vacuum test on the crankcase. I'm sure you will find a leak.

Ignition timing could be off if the flywheel moved.

Update
I bought the manufactured NGK plug, spark was better. Before testing that, I pulled the ENTIRE engine apart. It sat for 3 days and was bone freaking dry.
I reassembled and even without the carb hooked up, I shot just a bit of starting fluid in the cylinder and used the new plug and still nothing. That SOB should have at least popped. I am about to take this thing to the range and light it up with my .50Cal. I did fully reassemble and still nothing. No scoring, I cleaned the carbon deposits on the top of the carb, still solid compression, kill switch perfectly working, I can only think may the timing, but I do not see how that is possible with how basic the engine is. There isn't a belt, there are no valves. |

Try putting a vacuum gauge on the carb and see if it sucks when you roll it over.

Update
So I broke the entire engine down in pieces to inspect everything. The only thing I can see that may be an issue is the main crankcase seal as it had collected dirt/grim all along it on the outside and it is razor thin and fragile. Maybe as others mentioned I was having a vacuum leak due to a faulty seal.
So, I am going to order a seal kit for it, reassemble and give it a go, one more time, otherwise I am at a complete loss and may just toss it. |

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.
