wow oil temps seem high have your guages been calibrated as they can be miles out phil ----- Original Message ----- From: "Mark Langford" <n5...@hiwaay.net> To: "KRnet" <kr...@mylist.net> Cc: "Corvair engines for homebuilt aircraft" <corvaircr...@mylist.net> Sent: Sunday, September 04, 2005 10:56 PM Subject: KR> YeeeeeeeeeHaaaaaaaaa!
