Why is lower carb spraying gas out of the throat? Good spark on both cylinders, new plugs, carb taken off and cleaned
with no signs of blockage or stuck float. Motor runs but 40% power with lots of gas coming out???

Is your primer bulb holding firm with engine off?
Could be lower reeds or lower timing. If your lower timing is gone your reeds will probably need reseating as i found out this week on a 90hp

Check your lower reeds. They are not seating or broken.

If the powerpack or something had gone screw-wiff and had affected timing on the lower cylinder it might get a squirt back. Ive seen plugs put on the wrong cylinders damage reeds quickly
