I replaced the ROTAX throttle springs with weaker Harbor Freight springs. I always check the right carb spring in preflight. I found it separated today after 110 hours in service. The other one had also separated. The good news was the throttle response was fine without them. I would recommend that anybody using alternate springs do a no-springs runup before flying with them to know they are safe if the springs snap.
