Hello, my name is Jacob, and I am a Cub Cadet 105 owner. I am here because I am having problems, and hope the powers of the internet will come to my aid.
The 105 was a gift (hand-me-down). When it got to me it worked just fine, minus a few backfires here and there. I figured these were hill related and ignored them. It is even custom (I gotz headlights yo!) and great to mow on.
Then one day it happened. I turned it on, it ran for a few moments and then stopped. No amount of sweet talking or grass growing could get it to turn back on. I let it sit, did some other work, tried it, and poof! Right on it started... only to die a few seconds later.
So that is the current issue. If the 105 has been sitting for a while, it will start, run for a few seconds, maybe a minute or so, but then cut out. It may start back up, it may not. But if I let it sit, it will eventually start.
Here is what I did:
I used/abused Google/Yahoo! For hours. I found this:

And put some Marvel Mystery Oil in both the gas and oil. Been running it until it stops since to get the stuff moving through the engine. No change in behavior tho.
I got carb cleaner and sprayed it in there. A lot.
I checked the battery, it works. Just to make sure I changed the spark plug.

I looked for a fuel screen, but didn't find one. I found the fuel bulb (dunno what it is really called) and pulled it off. Gas easily flowed out of it. I then pulled off the float bowl. It too had gas in it, but I couldn't tell how fast it was filling.
So that is where I am. I suspect that it is a fuel issue. That fuel is not moving through fast enough to fill demand, and is only re-supplied over time... I just don't know where to go from here. I also suspect that it is something simple I am missing.
Also, and this is important, I only know enough about this to get myself in trouble. I could be wrong about my assessment.
