@Ken- Yah, that story sounds familiar. We've never had a problem with bikes. You get an old bike (70's) and you clean the carb and change the fuel lines. Seems to work. Outboards on the other hand, you get hard starts sometimes if the fuel goes bad, but there are other things you need to tune in the Summer as well. Them's the breaks when you don't have a heated garage.
But I can't tell you how many outboards we've got on the cheap and flipped for a few hundred bucks because of ethanol. What it boils down to is people think that leaving engines to rot preserves them, when in fact the opposite is true. You have to run an engine because they're made to run, not sit.
That's the fundamental truth in all of this. If you've got a running 2 stroke and feed it 50:1 it will run forever.
