It's been a while since I've torn into any small engine ... and I've never torn into one that had an oil filter so folks that work on these, please chime in.
There are some engines with an oil pump and filter that sling for lubrication and pump to filter .Cheap and really isn't the best it is like a bypass system in an old car .
