Weld,
Yes, it IS a bit of work to clean, the right side crankcase cover has to come off after draining the oil, But this exposes the oil pick-up screen for complete cleaning as well.... Two gaskets are involved (MAY need replaced), the larger case gasket is only about $3, so no biggie....
I'll cover all this again in the cleaning guide I'll post..... I'm thinking one posting in "Other Stuff" with a notice and simple links to the topic in the other sections......
I'll get started on the topic and post it ASAP...
Steve
