Have spark on all three cylinders, starter spins flywheel correctly, cylinder compression is 125 top, 127 middle, 175 lower. Lower cylinder carb pours out gas so guessing this is why the compression is so much higher since the cylinder is flooded, however the motor still doesn't seem to even try to start. I know that I need to rebuild bottom carb but still think the motor would want to fire off on the middle or top cylinders. Any advice would be helpful. Motor is a 90 merc. What is good compression for this? I figured anything over 90 is good.
