No, that's ok. Just thought it looked way different than any other RC engine I've seen before. The cooling system is normal for a boat, but the carb being mounted where the starter would go kind of boggles my mind a bit. I wonder how it times the fuel/air ratio in the crank case. On a normal 2 cycle RC engine, you have a timing hole in the crank shaft to load the charge into the crank case.
Kind of cool to see some of those older methods.
