    Default "compression and spark test fi

    "compression and spark test first, you can use a timing light to see if it has spark on each cyl. also it could be a carb flooding, with engine off pump bulb and look down carbs to see if any fuel is dripping out."

    Default "closed means no fuel to carb,

    "closed means no fuel to carb, open means fuel runs thru carb when running or pumping the bulb. if your boat has sat for more than a year it needs the carbs removed and cleaned, and each jet cleaned and verified to be open.
