I've pretty well got my mind made up, but I guess I need to write this any way. My buddy is getting out of the biz this year and he's trying to sell his 52" Ferris to me. I ran a comp. test on a 23 hp Kaw engine and got 120 from cylinder 1 and 90 from cylinder 2. Needless to say, this was alarming. Anybody have any ideas of quick fixes that could be causing this?
