Purge Bulb

The repair was simple. I removed the breather cover (two screws), then a plate that held the primer in place (4 screws). I then cleaned the exposed surfaces with a clean rag and Q-tips, put the new primer in place, re-attached the primer plate and breather cover. I primed the engine and it started on the third pull just like it always does.

Took out the four screws holding the primer. Pulled off plate and replaced the primer. Put screws back in. Worked like a charm. Spilled a little fuel but not too messy. Easy. Repair center would have probably charged at least $45 for that.

Primer bulb split after years of service. Ordered from a new one from replacementparts.com. Unscrewed two screws holding it in place and inserted new part and replaced the two screws. Part fit perfect as did all other parts from replacementparts.com. Delivery was fast and was using my blower within a few days after ordering new part. Sure beats buying a new blower!!

Empty the fuel tank or tip the blower on its side so the fuel won't run into the carburetor.
Remove the air cleaner element.
Use a #2 Phillips bit in a driver/drill and remove the screws that hold the carburetor to the blower motor. You can then easily remove the tubes to the carburetor. Make sure you remember which tube goes where! One is from the tank and goes to the primer/carb the other goes from the tank to the carb.
Use the #2 Phillips bit in the driver to remove the four screws holding the square plate with a round hole that holds the primer bulb. Be careful the entire carb assembly doesn't come apart and tear a rubber diaphragm or worse. Remove the plate and old primer bulb and replace the primer bulb with a new one and reverse the disassembly. Be careful with the driver if you use it to screw in the bolts. Start them by hand and then carefully run them in and then tighten them just enough. Use loctite blue if you wish. I didn't but then I've not had trouble with screws backing out on my echo blower.

1. Removed the screws on the flange that captures the primer bulb.
2. Removed the flange to access the primer bulb.
3. Removed and replace the primer bulb.
4. Reinstalled the flange.
5. Reinstalled the screws and tighten.

Unscrewed 4 screws (removed air cleaner to make easier screw access) replaced bulb. Really that easy.

Started by emptying the fuel, then took off the cover, and removed the tank. Ran the new lines into the tank, and connected them to the carb, then reassembled everything.

Loosen carburetor by loosening two screws. Remove four screws that hold the primer. Remove the old primer and install the new one. Put the four screws back on and tighten the two screws that hold the carburetor.

This maintenance was pretty straight forward. Replacing air filter and spark plug was easy. Instructions come with spark plug gap number so that you can adjust the gap yourself. Replaced fuel vent, filter and primer tubes which are easy removed and replaced. Replaced fuel filter, as it's attached to the end of a tube inside of fuel tank. You use a 4" wire and form a hook on the end of it in order to pull out the tube from inside the fuel tank. It has the fuel filter attached to it. Simple replace. I replaced the rubber primer bulb. It's attached by 4 screws to carburetor and easy to access. Just remove the screws and plate, then remove old bulb and replace with new primer bulb and reattach screws. This all took about 30 minutes. Very easy. You just need screwdriver, spark plug socket and wire cutters to cut a piece of wire with. Use a coat hanger wire or any flexible wire that you can stick inside the fuel tank.

Removed the old carburetor cleaned it and rebuilt it and replaced the fuel lines and purge bulb. Thank goodness for the you-tube repair video
