Had her out seveal times this summer and everything normal. Ran it on hose before taking it out a week after the last outing and it just sounded strange. Cranked up ok and idled and didn't sound like a miss. Started pulling plugs and #2 was room temp. Inspected plugs, gapped and swapped around, #2 still cold. Spark jumped a good 1/2" and very blue.
Hadn't had a chance to check compression.
I understand that each bbl of the carbs goes to a dedicated cylinder. If so, could this be a carb/fuel problem or a reed problem?
If a broken ring, does this mean a major tear down and involve all cyls?
This engine has never had a screw turned on the power head or anything above the lower unit.
Thanks, Mike

Start off by doing a compression test on it. Then maybe look into the carbs.
