I have a Fuji 50 and have found that it needs to really be primed in order to start. I have gone to using a prime bottle instead of priming with the choke. Set your prop up so that the magnets on the flywheel are coming up to the magneto pickup at the end of your flipping motion. In other words you want the prop moving as fast as possible when the mag is engergized. This gives you the best spark. My engine is a little hard to start at the beginning of the day but starts on the 3rd flip the rest of the time. I think this is because it needs to be really well primed to begin with.
