Re: pull starter
its pretty simple. When you pull the rope, a mechanism inside spins the crankshaft. when you release the rope, the mechanism sort of opens up and allows the crankshaft to move on its own. with our two stroke engines, engines that come with pull starts usually have a centrifugal clutch. but you can use a pullstart with a manual clutch as well, you just have to pull the clutch in and start the engine in neutral. you need a wider crankset to use a pullstart. standard width pedals will not clear a pullstart.
