Hi, Just found an Early 72 G5 serial number 2790. Needs a bit of work to get it running. Hate to part it out. Has spark but low on compression. Like to get it running. Need some help familiarizing myself with parts interchange with other years and models i.e. KE100. G5 specific parts are hard to find. I basically need a Carb / Kit, Gasket Set, and Ring set, maybe piston.Any help would be great. Thanks in advance.
