New carburetor for Echo PB-281 blower
This carburetor was an exact fit and my Echo PB-281 blower started on the second pull. It took only 15 minutes to change (2 bolts). I also changed all the gas lines and filters. The blower works like a brand new one.

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
