Took the boat out for the first time this year. When I got back I had a lot of transom soot. It started to do this at the end of last season, and I decided to wait until this spring to check into it. Spark plugs look good, and the motor sounds fine, but it's running very rich.
How do I adjust the carb to lean it out just a small amount?
All help is GREATLY appreciated!

yep, probably. If it ever backfired fairly hard, the diaphrams in the PV's are toasted.

Boat-less...

remove fuel lines. remove 4 screws holding on float bowl. remove power valve screwed in to the center of the metering block. rear size on valve. get new one. thread back in. install new bowl gaskets and remount bowls and fuel lines. Parts in hand, 5 minutes per bowl tops.
