Have not read if you have had success or not? Flew my plane with my ST3250, last week, died in mid-air and since then unable to restart. Doing all I know to do, would not restart. Engine although felt like it had compression, it didn't have the kick-back I am normally use to. Pulled head and looks like some slight scouring. Sent to Hobby Services for check-out, since engine only three months old. Hopefully you found something cheaper than this!
