The Babbit Bearings need to be replaced and the valve guides need replacing to keep the valves from wiggling and destroying the seal. The valves have been lapped and ll the moving parts lubricated. Took a while to figure out how to start it but it now starts after a few turns of the flywheel. A B&S muffler keeps the noise to a managable level. This motor was used at one time to supplement water pumping wind mills.
