well i order a oneway start shaft and it came with 3 pcs a spring,pin,and the crank shaft. look in the back of the gst 7.7 book with the pic of the engine and all the parts page 27. its part number G70357-35 or G70357-11. i am thinking about getting the roto starer this weekend eventhough i haven't put a gallen of gas through it. i guess everyone goes through pull starts during break in. my ct5 started up nice and easyly.
