I have a 1976 85hp Merc outboard motor and am wondering if anyone can tell me what carbs (there are 4 I believe)are on this motor, for cleaning and or rebuilding. The engine kills if I slow troll or try to trailer the boat leading me to believe that they are fouled. Don't think this engine has ever been tuned, so thinking that new spark plugs/wires/clean carbs will do it. Thanks for any help...Bombsaroy@aol.com
