Okay ... good info ... so the latch goes through a slot and is limited as to how far you can "swing it from side to side" - as you suggested I moved it as far as it will go to one side, now (and yes, I'm an idiot) the engine runs in one direction, at least, but won't go into neutral and do the reverse cycle, is there some adjustment so that the lever moves between - are we looking for 3 states? both directions / neutral no direction at all / one direction operation?
Thanks
