Re: "Classic" small, Japanese-based engines

[SCOTT BOGUE]

Carburetors are bound to be expensive, but for example, Crowley Marine has a gas cap assembly for a 1988 Yamaha 2 hp for $20 (just guessing about your motor’s age). I realize that you’re looking at used parts, but sometimes new OEM parts are surprisingly cheap.

That doesn’t answer your question about used parts availability. If eBay prices you found are typical, it would seem that anyone with a small Japanese motor that had some problem or another would part it out.

Good on you for saving a motor, even though it’s not your typical AOMCI fare.
