I just seen a video on youtube of a twin HP VT 49. I just got a couple of those engines and want to know how hard it is to make the twin. I have never rebuilt an engine and dont have very much experience but some of the club members are really good with engines and wouldnt mind helping. If anyone has experience with this please let me know...thanks[link]http://www.youtube.com/watch?v=euUP4MpIzYY[/link]
