wet with fuel ? check fuel pump

Check compression and then check spark with a spark tester on all cylinders.
If all OK the look at the fuel/carbs. too much fuel or not enough will not let the cylinder fire the mix properly.
#1 cylinder will not be affected by a hole in the pump ,that is usually #3
