  • I can’t get my cylinder to fire



    I have a 1990 johnson gt 100 outboard

    my top left cylinder won’t fire. I have new plugs and ignition coil.. I get a spark but doesn’t ignite.. I checked the gas line to that cylinder and gas is coming out of the line.. the carb was super clean.. don’t understand why the cylinder won’t fire! I get 105 compression in that cylinder aswell

    Does the spark on that cylinder jump a gap of 7/16" or more , yes or no ?-----Checked the reed valves ?
