After watching a bunch of YouTube video's about Sea Foam I figured I would give it a try on my brothers B100. I filled a garbage can with water and fired the old girl up. Once it warmed up enough I gave a few shots of Sea Foam. As expected the exhaust came out blue. And lots of it. I kept giving it shots while revving the engine so it wouldn't stall. After a few blasts and letting it run, I sprayed enough into the carb to stall the engine and let it sit for 15 minutes.
This is how the water looked after I fired it up and burned the Sea Foam out. There was a LOT of crap in the water.

The second round of Sea Foam did the same thing to clean water.

Sure glad I did this in a garbage can of water and not in the lake like I've seen on some of the YouTube video's. I wouldn't want to have dumped all that crap into the lake. I was hoping to try the motor out, but the rains came in shortly after I had given the engine a scrub at the car wash. Maybe tomorrow if the weather is good.
Although it may be my imagination, it does seem like the idle is better.
