If money's tight and you want a great powerful reliable engine then get the Supertigre engine. They run great with little need for you to ever pull it apart and fix it to run right, they've got a 3 warranty, and come cheap. Personally i'd get a Super tigre over anything but a Jett engineering engine any time!! And those are expensive engines.

My 51 ringed puts out a crap load more power than a buddy of mines O.S. out at the field while I'm swinging a 11x6 hes swing a 10x5 and I'm still kickin his engines a**.
