Yep, the filter was changed and will be at every oil change. Now if I can only get the darn thing to stop digging up the lawn on sharp turns I'll love it.
I have a 1024 with the 24 horse Briggs with 260 hours and I have only changed the oil and filter once in its life, and just changed the oil when I did the case half gasket, It was clean as a whistle inside.
250 hours.
