Scale Bud Nosen 1/4 Scale Cub?


70cc twin V2
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.
