Definatly get the os37 ringed. It makes a lot of power for a 30. On the other hand, it's not a whole lot more to start with a 50, and I'd consider that over the 30 if you can swing it.
A ringed engine is just that the piston has a ring on it to seal the combustion chamber, a non ringed engine merely uses "pinch" a progressivly tighter fit as the piston moves towards the top of the stoke.
Thanks a lot bgjames111 i'll have to look into jumping to a 50. thanks again.
