I'm having a world of crap tryin to get this engine to run,i kept snappin my pull starter so i got a geared drive so you can start with a drill but I'm not having any luck gettin it goin,i turn all the needles back to spec and it still wont run,new glow plug,odonnel racing fuel and a hot ignighter,i had it goin before for only a min but snapped the pull start and since replacing it I can't get it to run?????????????I'm almost positive its a good engine,so i was wondering if my cordless 12 volt is fast enough to turn over the engine?
