That's an old one. I have access to the dealer system and tried to pull up the PID, not in their US-based system so it could be a worldwide model. Real similar to the C25 but not identical. Was a low end 25, twin cyl single carb, no frills. Decent motor as long as it doesn't need any parts. Parts are scarce for them; and some parts for even the twin carb 25's up to 2007 are getting harder to find too. It's almost as if they aren't interested in 2 stroke stuff anymore, which is fine with me. I worked on a few of them back in the early 1990's. Real rough running as I remember.
