Poulan Pro PP4620AV

2-Stroke

The Poulan Pro PP4620AV is a 46cc 2-stroke chainsaw and the top model in Poulan Pro's consumer lineup, suited for regular firewood production and medium-diameter tree felling with a 20" guide bar. The AV suffix indicates anti-vibration dampening. Built on the Husqvarna-shared consumer platform, the PP4620AV delivers more torque than the PP4218A for handling larger logs and tougher species. It 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. Chain and bar maintenance is more critical at this displacement.

Verify before ordering: Fitment can vary by serial number, production date, region, and sub-model. Match the OEM number and physical dimensions before ordering.

Tune-Up Kit

Common service bundle: spark plug, air filter, fuel filter, carburetor, primer bulb, fuel line kit.

Maintenance Interval

Inspect filters and fuel lines each season, replace spark plugs during annual service, and service carb/fuel-system parts when starting or idle symptoms appear.

Before You Buy

  • Confirm the full model is Poulan Pro PP4620AV, not just the family name.
  • Check serial number, production date, and regional variant before ordering.
  • Match the old OEM number stamped on the removed part when available.
  • Compare dimensions, plug gap, thread, fuel line diameter, or chain pitch/gauge where applicable.

Common Mistakes

  • Ordering from a family listing without checking the exact sub-model.
  • Buying a kit that includes the headline part but wrong gaskets, lines, or bulb size.
  • Choosing the wrong carburetor revision when multiple versions were used.
  • Assuming all fuel line kits use the same diameter and routing.
  • Installing the correct plug number with the wrong gap.
  • Matching bar length but missing pitch, gauge, or drive-link count.

Replacement Options

Best OEM equivalent

Start with OEM references 952030150, 545057701, 545038502, 530071693 and match the removed part before choosing a listing.

Named part options

Cross-check named parts such as Champion RCJ7Y (spark plug), Stens 605-504 (air filter), Stens 610-035 (fuel filter) against the OEM number, identity label, and dimensions.

Best for annual tune-up

Bundle spark plug, air filter, fuel filter when servicing the Poulan Pro PP4620AV at the start of the season.

Best if replacing fuel system

Compare the fuel filter, carburetor, primer bulb, fuel line kit together so line routing, bulb size, filter style, and carburetor connections match.

Best chain/bar combo

Match chain specs together, especially pitch, gauge, drive links, and bar mount details.

Best budget kit

Use kit listings only when every included part matches this model page; cheap kits often mix correct headline parts with wrong bulbs, lines, or gaskets.

FAQ

Should I buy OEM or aftermarket parts for the Poulan Pro PP4620AV? Use OEM when the part controls fuel metering, ignition, or safety. Aftermarket kits can be useful for routine filters, bulbs, plugs, and tune-up bundles when the OEM number and dimensions match.

How do I avoid ordering the wrong carburetor for the PP4620AV? Match the carburetor number stamped on the removed unit, then compare linkage, choke setup, primer routing, gasket stack, and fuel-inlet direction.

What should I check before replacing fuel-system parts? Photograph the old fuel-line routing, match line diameter and filter style, and compare primer bulb size before buying a kit.

What chain details matter besides bar length? Match pitch, gauge, and drive-link count against the bar stamp, old chain, and drive sprocket. Bar length alone is not enough.
