Product Description

?

This is a genuine Echo replacement part and is sold individually. Its propose is to deliver an electric current from an ignition system to the combustion chamber of a gas fueled engine. It will ignite the air fuel mixture by the spark. Spark Plugs will usually have to gapped to the manufactures specifications found in the owners manual. Over time a Spark Plug will become fouled because the air/fuel ratio may be set wrong, worn piston rings, carbon build up and other factors. It is better to replace a fouled spark plug, rather then trying to clean it.

Echo PB-603 Backpack Blower is 16 years old and engine would die if throttle was pressed

Followed eReplacementParts video, a couple of YouTube videos, and the backpack blower owner manual to complete all repairs. Several bolts were rusted when I disassembled the blower parts. I sprayed them with Seafoam Deep Creep penetrating oil to clean them before I reassembled on the blower. Before I ordered the parts from eReplacement Parts.com, I had the Echo re-power parts (new spark plug, new fuel filter, new air filter). Changing these parts didn\'t do anything to fix the issue with the engine dying. While changing the other parts and performing routine maintenance, I found that the exhaust gasket, insulator and fuel pipe all needed to be replaced. I ordered all of these parts plus a new carburetor from eReplacementParts.

All of the parts received from eReplacementParts were OEM parts and high quality. The new carburetor completely fixed the issue I was having with the blower and it is running just like when it was new.

Changed out the purge bubble & spark plug. Almost got it to crank over. The replacement parts were on time, exact parts I needed. Thank you. I think I might need to rebuild the carburetor next.

1. Took all the lines out of the gas tank
2. Placed all the lines beside all my new parts and used it as my guide
3. Once I got all the pieces together I pushed the grommet back into the tank (not an easy thing to do)
4. I then took the old primer out and installed the new one, making sure I didn\'t get any dirt in the small hole for the gas to feed the primer
5. I replaced the old air filter with the new one and again you have to make sure you don\'t get any dirt in the area.
6. I took the new spark plug and compared the gap to the old one making sure it was the same
7. I then turned the trimmer over and replaced the screw that had been lost
8. I then greased everything and started my trimmer
