This blog is a step-by-step instruction for replacing the carburetor on a ECHO leaf blower. The most common reasons for replacing the carburetor are when the leaf blower won’t start or is hard to start.

Replacement

Before you begin the replacement, you need to make sure the engine has cooled and the on/off switch is in the off position. We recommend performing this procedure with little or no fuel in the tank. You also need to remove the wire and boot from the spark plug to prevent the engine from accidentally starting.

Step 1: Unthread the wingnuts counterclockwise to detach the air filter cover and remove the air filter. Use a t27 Torx bit to unthread the two mounting bolts securing the filter base and carburetor.
Step 2: You can use pliers to help detach the throttle cable. Note the orientation of the fuel lines then detach them from the carburetor ports.
Step 3: Install the new carburetor by first attaching the fuel lines to the appropriate ports. Hook the throttle cable onto the lever and make sure the baffle is in place in the air filter base.
Step 4: Then insert the bolts, position the carburetor intake gasket on the bolts and align the carbeutor followed by the outlet gasket.
Step 5: Now position the assembly and thread the mounting bolts, replace the air filter, realign the filter cover and thread the wingnuts to secure. Refill the fuel tank if necessary and your leaf blower should be ready for use.
