Resource Page for Echo PB-413H Backpack Leaf Blower

I purchased the Echo PB-413h backpack leaf blower back in 2007 to replace my older Sears handheld blower. It has served me well over the years but I am starting to experience problems.

I spent many hours collecting information about my leaf blower so I figured I would save some time for you and share what I have. If you have additional information that I missed, I would appreciate it if you can leave a comment to let me know.

CARBURETOR

Zama was originally founded in 1952 and incorporated in 1980 in Los Angeles California. After considerable growth, Zama relocated its headquarters to Franklin Tennessee ten years later. In early 2008 Zama USA was purchased by SIIX Corporation and IIDA Denki Kogyo Co. Later in 2008 Zama Japan and Zama China were purchased by Stihl Group. Today Zama is a leading diaphragm carburetor manufacturer for the outdoor power equipment industry.

There are many different models of Zama carburetors and likewise many parts available to service them. There are usually two identification numbers located on any Zama carburetor model. One number identifies the body type and the other identifies the model code. These two numbers combined will identify the full model number required for parts identification. Using the application charts on our site will aide in identifying your carburetor model and required carburetor parts or kit. We also suggest visually checking the body type and model code located on your carburetor for confirmation.
