Its a shame you dont have any hills near you, something I take for granted here. Best get two of your mates. Ignition on, select third gear you on the bike holding clutch in, choke on and just a crack of throttle opening. mates shove and when going at a good speed you let out the clutch, be careful the bike doesnt shoot off with you if it goes, mates continue to push until its running or they collapse...whichever happens first If it doesnt even fire, check for spark again and take note if the plug is wet with fuel.
fingers crossed
