First thing I'd do is install the correct heat range plug and go from there.That'd be Champion J4C gapped at .030".If you troll mostly ,you can increase gap to .035" or .040" to prevent wet fouling.Wet is at least an indication the carbs are passing fuel and the dreaded lean condition isn't present.

Jethro66,

Do you have some kind of service manual for this motor??

Check spark on both cylinders with a spark checker from your local discount auto parts store or make one. Do a search for spark tester and you will find a thread that tells you how to make one. You may just be losing spark to a cylinder and running only on one. Make sure you put the correct plugs in like ob said.
