RE: Top 10 list of convert-able engines?
the john deere is most likely an echo/kioritz, the eager beaver is an 80's copy of the kioritz but isn't quite as nicely built (roller bearings) but they sure are light
the craftsman blower is most likely either the 32cc ryobi style or a 25cc poulan
I'd trade a couple engines with you if you wanted a ryobi or two...
