Nice RysiuM,
were did you get the linkage? Are there plans to port this engine? Stuff the case? maybe test a bigger carb? Did you run a compression check? Did you degree the motor?
Mine is on the bench. I have a Carr Precision prop hub and mount. Same muffler as yours. Hope to have in together in a few days. I've been following your posts in the glow/gas and I know the mix works on a homelite.
