RE: Saito is the best four stroke glow engine.
I used to think the Saito engines were "Not attractive" to the eye, the cam driven gear case does obtrude somewhat. However, being a long time lover of radial engines the Saito cylinders are beautiful to me.
Every other four stroke just looks like the cylinder of the (Bleah!) Honda engine on your log splitter. Calling the others good looking is like praising the texture of the concrete in your sidewalk. All the same.
