About this kit

Echo built the PB-250 with two different carburetors over its life, an RB-K106 and a WTA-33, depending on the serial number. This one is the RB-K106, which replaces Echo A021003660 and A021003661. Check the stamp on your old carb and you will know in five seconds.

The H and L screws come without limiter caps, so you can bring a tired engine back to full power after installing. Two gaskets, two bulbs, two air filters and a spark plug come with it.
