I have two of those craftsman 32cc engines, one weedie and one blower, both are probably going to be used as project RC stuff... (the blower I got mostly dissassembled and the weedie I got from a trash can without the clutch bell and some other clutch parts... but free was free...) they are very close to the ryobi engine in first apearance but the flywheel schroud is molded to the block, the backplate is friggin huge (it has the fuel tank and exhaust heat shield molded all in one piece...), the fuel lines are tiny to the carb, the muffler is odd, it's outlet is all the way around the outside, kinda nifty looking.

when I get bored enough and have my lathe working (need a bigger chuck to make prop hubs, right now it only has a 19mm drill chuck) I'll play with the weedie one and see if I can get it running good, maybe use it to play with internal modifications , after that maybe I'll play with my homie 25... then there's the lawnboy or greenmachine or whatever it is... (old stihl clone with barrel carb)
