Buc, Engine looks pretty clean, that gummy caked on block looks like oil that came out of exhaust ports. Those pistons look like new yet, can’t have much run time on engine, with good compression that it has, sounds like Tubs may be on-to something. When I was learning about engines at local Vo-Tech, they always pushed about exhaust ports being plugged, from using different types of oil. The rule was Compression, Spark, Fuel, Exhaust Ports & muffler on 2 cycle engines. Do you have an Ultrasonic Cleaner with Heater, for cleaning carbs?. I bought one for the garage 2 years ago to use on small engine carbs, and couldn’t believe the crap and particles that come out of carb. I know that I must have condemned some good carbs that were just dirty or plugged. It’s a good tool to have in the shop, kinda like having a Merc-o-Tronic to test ignitions. To have the correct tools at your side to help you diagnose certain problems. Just think how much time you would have to purchase a new professional test tank, with hydraulic lift, with exhaust port, test wheels, and being able to run those outboards at full throttle, and no more backaches.
