Makes me sad that these aren't available in 5/8" straight shaft. The tapered shaft engine + 4G is too wide on LHS for my setup.
Been thinking about trying to make a "frankenstein" motor someday. GXH50 lower case half + offset-ground GXH50 crank; 144F upper case + piston and custom rod. Might be about 55-56CC and a lil bit over 3HP with 9.5:1 compression. That is if it would all bolt up together!
