hi- when i start my 90 h.p. ,i get alot of white smoke.The motor is in great shape and other than the usual hard start while cold,have had no problems with it.I just changed the fuel filter and put the muffs on to run it in the driveway and the white smoke just kept coming out of the exhaust(prop shaft).Is this normal?Ive never had this happen.any ideas? thanx
