I will make this as brief as possible...<br />last year when having trouble with my 1989 Johnson 60...the mechanic replaced relays and tampered with the choke, didn't fix the problem, charged me $400...and also showed me one cylinder had low compression. This year the problems continued...really hard to start...won't stay idling...bogs and dies when you give it gas. I changed the Choke Soleniod and a fuel line and adjusted the carbs so it would at least start, but still would bog when accelerating and was running real rich. The director of one division of our Bass Tournement Circut happened to be fishing with us one saturday and has been a marine mechanic for 40 years. He walked over to my boat...listened to it a second and said..."only running on two cylinders"...he played with the carbs...it now starts every time and runs without bogging out but has much less get up and go. Two others I have talked to said that the old guys diagnosis is very possible. Heres my question...thinking on rebuilding the powerhead. I am not a experienced mechaninc but am told that if I have the manual and an experienced someone to answer questions I should muddle through okay. If ytou guys had to give this job a difficulty rating from 1-10 (10 being a job for a pro) where would you rate it? ( I am capable of about a 5 or 6 rated job). Should I have the cylinders walls tooled or only if they are scored and/or pitted?
