Go to club Saito and you will learn everything you need to know about your new engine. I started mine the first time with an electric starter and had to turn the engine backwards against compression and then start the starter and hit the engine with it. Some of them are tight and a little hard to start at first, but after you get it running a few times it gets easy. Most of the guys at my field don't even use a starter. They just use the spinner and their fingers and spin the engine backwards and it fires right up.
