Thanks for all the information about the O&R engines, I have gained a ton of knowledge here.... I have gathered up three 1 H.P. O&R engines to date for a Lil Petro micro mini bike restoration, learned a bunch about the engines here. I saw the thread with the gear case tear down and reassembly and he used Lubriplate 105 for the assembly, but is it also used for operation?, or was oil added to the gear case? It has been suggested that 30W oil was used in these gear cases and there is both a fill and a level hole on the case. My main concern is to do no harm. Looking for any insight you guy;s might have.....Thanks agin for all the great info.
