Well mine is a late B and not a 50 but I have never ever seen white smoke out of it at any time whether warmed up or not so I don't think that is your problem. Also if set properly have never seen 1/2 turn work on idle screw. When warmed up set throttle lever wide open and with load screw closed open idle mixture up until it stumbles slightly and then back in 1/2 turn. Maybe he meant to start out at 1/2 turn to get it started to get warmed up. Back to the white smoke...these things have a crankcase ventilation pump which evacuates blowby out of crankcase into air inlet to carb. Is there somewhere it maybe getting rain or leakeage into crankcase. White smoke in gas engine is moisture. RB
