I've had a PW50 in the shed for 10 years and am going to bring it back to life this spring. I think it got parked because of carb troubles in the first place. "Sorry, we don't sell PW50 carb parts anymore" is what I get at my local shop. Before I get started, is there still a reliable oem spec parts seller for these or is used the best I'm going to find? I'd be willing to order a carburetor jetting kit for it before I even touch it, it's going to need it. Suggestions? edit: I read that the carb from a z400 ATV is a close match?
