Thanks! I don't need it right away, never dealt with a flooded crank case before where it is too wet to ignite. Its already on its side, exhaust port down, and plug out. I will let it sit till its bone dry. Thanks for the help guys. |

I've taken the spark plug out and used my lit propane torch pointed in the plug hole and pulled the starter rope.
It will suck the flame out sometimes but just re light, it will "burp" a few times usually clearing the cylinder as well as the crankcase of fuel. Also check for mud dauber clay, plugging the little exhaust hole in the muffler. Every year they plug several of my weed wackers as well as the leaf blowers. They will also get into some air cleaners, even carb vent holes. On a two smoke, they will absolutely not even "pop" much less run, with the exhaust plugged. |

Something I didn’t realize until this year when I bought my new Echo blower is these things want higher octane fuel. I went back and checked the manual on my Husqvarna weed eater and it said the same thing, at least 89 octane.

I had the same thing happen last summer. Turned out the screws holding the cylinder to the crankcase were very loose. Crankcase would not develop vacuum to suck in fuel. Tightened them up and it ran like new.

Any chance the flywheel has sheared the key and it's out of time?

Well, put it back together after breathing for over a week. couldn't get it going again, took it back apart again and let it breath for another week or so. Sprayed a bit of starter fluid into the cylinder and still absolutely nothing.
Thinking I am going to pull the motor off to see if the clearance has issues or somehow the timing is off. |

Nothing wrong with checking the timing. How strong is the spark? do you have one of those gizmos you plug "in line" to check for spark? If not, do you have an old plug you could sacrifice? If so set the gap on it BIG, talking 1/8" or more. Rule of thumb when I rebuild magnetos is they must fire a 1/4" gap, yeah you are working on a little engine but the concept is the same.

I can see spark but I am thinking it may be weak. I was going to pull the engine to get at the ignition on the flywheel to see if it was rusted on the magnet making a poor connection. I do have another spark plug that I can sacrafice I will try that. The plug looked a little wet nothing like it was in the past. I then dried it off and tried the starter fluid and nothing. I even hooked a drill up to the pull start and cranked it probably 100 times and nothing. |

While it is whirling over stick the lit propane torch in the plug hole to burn any accumulated fuel out of the crankcase/cyl. Again, is the exhaust clear?? they will not even put, much less run with it clogged. |

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.
