Just got a motor for local dealer. I know nothing about motor (it does turn over) dealer said he was told it started but recoil rope was broke. It is a Clinton 5.5 hp model K550 6000A S/N 1586625 What year, what gas mix, what oil or grease is used in l/u. Spark plug # and gap? points? What is reasonable compression. A quick look it appears to be air cooled (no waterpump)? Were can I find exploded view of parts on Internet. Thanks
