repowering my 1972 simplicity snowaway. The 6hp L head briggs is getting tired. Installing a Honda GX200 6.5 hp. Had to redrill the mounting holes to center the crankshaft. The height was to low,used briggs 1" spacers and had to get a pulley sleeve to from 3/4" to 1" e-bay worked great. Had to put a deflector on the muffler to point it outward. This engine off of a pressure washer, will I have to make a hot air box to keep the carb from freezing up?
