This is a pretty cool engine. It is fairly large, for it's displacement, though.
The carb is on the side of the cylinder, and I'm trying to visualize if rotating the carb will allow the throttle linkage to operate in a front-to-back motion, rather than the vertical arrangement that it is set-up with, now. I should have had a picture ready for this, before I made a post about it. Hang loose- I'll catch up and shoot one soon.
If bench running goes well, I will make a neat airplane for the circles. It doesn't have to be on an R/C model! Then, I'll be the only one out here that has a F/S on a C/L plane. (that I've seen) Ha ha!
