Contacted Walbro tech support today and they confirm that the replacement carb is WBD-18. Now the problem is I don’t think that carb is available anywhere. I’ve contacted Husky and am waiting for a reply from their tech support and will be contacting Walbro again tomorrow. I’ll just have to wait to see what they have to say. The carb Blaz posted is not the same and has a different Husky part number. Thanks to those who are trying to help me out.
