Click on the link to the carbs in your first post. Find the Walbro number and google that number. I am pretty sure they originally came with Zama carbs, but it looks like the Walbro is direct replacement.
Look, maybe you will love it. I kept buying them because that's what the dealers were pushing. I didn't realize there was better stuff out there. It was not until I got away from them that I realized replacing carbs and scraping exhaust ports was not routine maintenance.
