About this kit

The BP42 runs a 4-cycle engine, so it does not burn mixed fuel, but its small float carburetor still varnishes if gas sits in it. Our replacement follows Ryobi 308054079 and 308054093, and the air filter matches 900777005.

Two fuel line connectors and an adjusting tool are in the box, along with gaskets, a filter, a plug, two lines and a bulb. The same kit fits the RY08420 and RY08420A backpacks and the RY42WB wheeled blower.
