i have recently bought a 1977 evinrude 35hp outboard with a jet. i live in montana ele. 4500ft, motor came from missouri -500ft? plugs are showing way too rich with the low speed idle backed out 2.25 turns (dont want to fry it). yes, i will compression test this weekend. i understand it could be a jetting issue, but i think i have more of a problem. first some of the wire casings were melted when i recieved it. i can tell it has had a new headgasket done in the past from the paint missing, but not been completely torn into. i was TOLD it has a compression of 139psi in each cyl. what it sounds like is its not putting out the power for the rpm its giving, and its got a (double) miss at full throttle. bottom line its not getting my 14ft up to a plane. i also have a tach dwell meter that ill try to check rpms 5500-6000? does anyone have any exp. with this or know for sure? any ideas?
