I'm currently waiting for parts to put my 30hp Kohler back together. I have a few questions. When I put it back together what is the best way to prime the oil pump? What oil would you recommend? I've always heard not to use synthetic, because the rings won't seal right. I want to put the best oil I can in it. I'm putting new rings and head gaskets and replacing all the seals. Any tips you have when putting these back together? Is there a break in period? Thanks in advance guys.
