Thought I'd share a project I completed last week on a 10550 I bought that would not stay running.
I completely stripped it down and sent the deck out to be sand blasted and powder coated I used RAL 6018 powder which is actually Kawasaki green and it's a pretty darn good match. Cleaned the carb and put in a Larger pilot jet. And used some scotch brite on the coil and flywheel magnets to remove the rust. Replaced all the wheels with commercial steel wheels. Reassembled and cleaned up all the parts as I put it back together it also got a brand new tri cut blade
The best part was after it was all back together and looking pretty good it started on the first pull and ran great so I mowed the lawn and got it dirty. That's what I built it for here's some pics
I only had to pay for the powder a friend of mine blasted it at his work and I work for a company that powder coats parts so I bought 2 lbs of powder and probably have enough left to do two more
