Right... flooding the cyls with fuel washes the oil off the cyl walls and causes excessive wear.

The 11-14 bounce and flooding on decel sounds like it could be a bad power valve or even a mismatched/bad/shrunk metering block gasket.

My guess was the power valve. It's been sitting 10 months. Had gas on it but emptied 10 months ago. Could be the meter block gasket. I'm replacing everything to be safe.
