First I pulled the fuel hoses (2) loose from the carburetor then removed the two screws that hold air cleaner assembly and carburetor. Disconnected the throttle cable from the old carburetor. Connected the throttle cable to the new carburetor and remounted everything and fired the blower up. Works Great. Repair time less than 30 minutes.

I did keep the old carburetor and plan to rebuild when I get a chance. It is a lot less expensive to rebuild the carburetor, but it is time consuming.

Hope this helps
