Scale Bud Nosen 1/4 Scale Cub?

Looked at the valves and they are good. Looks like one is a little tight and needs gapped. The jam nut on the other probably needs replaced as well. Looks like the wrench slipped on the previous owner when he adjusted it. The gap on that one looks good, but I'll check it with the feeler gages. I will bench run it and make sure the needles are right. I will prop it with a 19 X 8 and see where the rpm's are. I'm going to shoot for 7300 to 7600.

Pulled the top off the GF40 and cleaned all the carbon off the valves and head. The piston came clean with a wipe or two. Adjusted the valves to .05 gap. Cylinder walls look good as well. Cleaned the carb to boot.

Ran the engine for the first time and I'm very happy with the engine so far!!

Agree! Don’t have any experience with four-strokes but I really like this one!
