Hello bivnq,

I contacted the factory regarding the 8308360 purge base to see if there may a replacement for it. They said it is no longer available a an individual part. That the only way you can obtain it, is by getting the complete 12520008665 carburetor assembly. You may want to try one the many Echo service centers around the country to see if one might have it. Also look on the carb. to see if you can see the manufacture of the carburetor, if you can locate that you may be able to get it from them.
