i have a 25cc homy and a 30cc and i can start both with a couple of flips.both of mine have the walbro flywheel and coil.it just takes a little practice and the right procedure.put finger over carb and rotate to get fuel in engine,wet.put the magnets at about the 2 oclock position and alighn the prop with the magnets.put two fingers on the prop face and flick and push in a fast movement.its not power but speed that gets them started.you have to remove the pullstart also.
