1806 issues
I had some time this morning so I spent it checking out the 1806 I picked up. It has two major issues, one moreso than the other. The left cylinder has no compression and the clutch, although it works, has something not right about it. I'm hoping the lack of compression is, fingers crossed, just a stuck valve, I'm just not sure how I want to attack it.
Is a stuck valve from sitting too long common with these Magnums? Easy to free up or a major problem? Any and all suggestions welcome.

Best thing to do is send it to Tennessee. I would like to have one of these.
Just messing with you. I have never had one apart but Mr George will along with some good words of wisdom.

You can pull the breather covers off to see if the valves are moving. I had a M20 with a stuck valve and was able to free it from there.

I determined the piston was moving so I shined a superbright LED beam down the spark plug hole and saw the exhaust valve was not moving. I gently inserted a wideblade screwdriver in the hole and with the blade between the valve and the head I twisted the blade gently putting pressure on the valve. I heard the valve spring back so I checked with the light and it had seated. I ran a compression test and now had compression on both sides. I replaced the spark plugs and started it up. Runs smooth now.
Next issue, the driveshaft and clutch.

Hopefully with regular use, this issue will not return. A tight guide, or weak spring can cause this. Glad it's working well again.

Normally the opposed twins don't have sticky valves as they are horizontal valves
But one that has set unused for a spell, can stick. I'd not loose sleep worrying that it will stick again. |

That's excellent. A person doesn't get too many fixes like that.
Glad it's running for you. Ken |

Hmmm, I think I found the clutch problem. You don't think the bolts instead of pins, the bent plate, the broken discs, the wornout pivot pin, and the off-center throwout bearing might have anything to do with it?

That's quite the mess.

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.
