Hobbico makes two "standard" starters, the "90" and the "180". I have the 180, and on two of the normal 7ah hobby batteries in series for 24v, it will turn over my 50cc gasser (DA 50). I'm sure it will do your engine, either on a bigger 12v, or on 24v. I can't say if the 90 will handle the extra power or not.
