I'm going to the Billy down under tomorree to pick up my newly aquired 448 and I would like to do a check on the compression before I drag it home.
I need to know a few things since I've never laid eyes on a 18hp Onan motor . I need to know do I have to take the engine covers off to do the comp test and besides the comp gauge what other tools do I need to take? I went to the parts manual & service manual section and the pages aren't fully loading including the ones I need.
What size plug wrench do I need to take and what do I need to take to remove the engine covers off if that needs to be done? Thanks.
