Stuck or broken reed valves, faulty carburation, faulty fuel delivery

Re: Mariner 9.9 International wont run

Double check your spark and bypass the kill switch. Are the plugs wet after attempting to start or are they dry (dry, no fuel: wet, poor/no spark).

Not certain of your serial #, but you may have stuck check valves (instead of a reed valve) located in a plate behind carb.
