Poulan Pro PP4218A

2-Stroke

The Poulan Pro PP4218A is a 42cc 2-stroke chainsaw and one of the most popular entry-level chainsaws sold in the United States, commonly available at home improvement stores with an 18" guide bar. Built on the Poulan Pro consumer platform shared with the Husqvarna consumer lineup, it suits homeowner firewood cutting and occasional felling of small to medium trees. The PP4218A runs a Zama carburetor and uses NGK BPMR7A or Champion RCJ6Y spark plugs. Common maintenance items are the air filter, fuel filter, primer bulb, and fuel lines. A high-value option for first-time chainsaw buyers.
