hi everybody, i'm new to this site, and to mercury outboards. the problem i'm having is with a 1964 650 merc. it is not firing one the #2 cylinder. i have rebuilt the carbs, cleaned and checked the magneto(points,cap,and rotor). done a compression check( all cylinders between 120-125). firing good and 1,3,and 4 cylinders. good spark on all plugs when out of powerhead, and all cylinders seem to be getting enough fuel. the new plugs are firing, with the exception of #2. looks like a brand new plug after running. any help or suggestions would be greatly appreciated. thanks for the time to help. chris
