what is the best engine under 120? towerhobbies brand? OS CR-X? i really want a pull-start, if it's 125 i don't mind 5 bucks but i don't want to get carried away. But, if it is a good engine i'll pay a little more, not too much... what ever works.
(first timer with the engines, my TRX pro seems to be dead, it has compression yet no one can tune it, replace the carb )
