Doing a pressure wash is always good as a clean machine is nicer to work on and easier to see problems. I would suggest that you also get an engine cleaning gun, they can get into more confined areas and won't generally blast back into your face like a pw does. Harbor Freight has them on clearance for under $6, fantastic value.https://photos.app.goo.gl/5e4ApMHsz9bygxkL6 https://photos.app.goo.gl/BkNGRKc8rqLHX2hQ6 Everything seemed to be on the right side. I plan to pressure wash it tomorrow.
