Poulan Chainsaw Spark Plug Parts

Poulan Chainsaw Spark Plug Parts

A worn or fouled spark plug is one of the quickest fixes for a Poulan chainsaw that won't start or runs rough. The spark plug ignites the fuel-air mixture in the engine cylinder — when it gets carbon-clogged, gapped wrong, or simply ages out, ignition fails and your saw goes silent.

Poulan chainsaws use standard small-engine spark plugs, typically Champion or NGK types matched to your model's heat range. Getting the exact heat range matters — too cold and you'll get fouling in low-speed cutting, too hot and you risk pre-ignition. Replacing the plug is a 5-minute job with no tools required on most models.

• Spark plug won't fire: Carbon buildup on electrodes, cracked porcelain, or corroded terminals — clean first, replace if cleaning doesn't restore spark
• Black, oily plug: Carburetor running too rich; clean or rebuild carb after replacing the plug
• White, clean plug: Carburetor running too lean; adjust fuel mixture or check fuel line
• Incorrect heat range: Too cold (fouling) or too hot (pre-ignition); use your model number to confirm OEM spec
• Plug gap drifted: Gap should match spec (usually 0.020 to 0.025"); reseal or replace if out of tolerance

Poulan Chainsaw Spark Plug FAQs

What heat range spark plug does my Poulan chainsaw need?

Poulan chainsaws typically use Champion RJ19LM or NGK BR2LM as OEM plugs, but heat range varies by engine displacement and model year. Check your owner's manual or use your model number to confirm the exact part number — ordering by heat range alone risks fouling or pre-ignition damage. The correct heat range is matched to your engine's typical operating temperature.

Why does my Poulan chainsaw plug keep fouling?

A fouled plug (black, oily coating) almost always means your carburetor is running too rich — the fuel-air ratio is off. Before replacing the spark plug repeatedly, clean or rebuild your carburetor. A new plug will foul again in the same conditions. If the carb is clean and you're still fouling plugs, check your fuel line for cracks (old fuel = gummy deposits) and confirm your air filter is clean.

Can I use any universal spark plug in my Poulan chainsaw?

While many small engines use standard spark plug sizes, the heat range is critical — and it varies by engine size and year. A universal plug in the wrong heat range will cause problems. Always verify your model number with the OEM spec to avoid fouling (too cold) or pre-ignition (too hot). Poulan models from different eras and displacement classes need different plugs.

How often should I replace my Poulan chainsaw spark plug?

Most small-engine spark plugs should be replaced annually or after every 100 hours of run time, whichever comes first. If you store your saw for the winter or off-season, replacing the plug before the next cutting season is a smart maintenance move — old plugs corrode and gap drift during storage. A fresh plug is a $5 to $10 investment that ensures reliable starts.

Poulan Chainsaw Model Number: Where to Look

On Poulan chainsaws, look for the model number on a label attached to the powerhead housing, near the rear handle, or under the top cover. Clear away sawdust and check both sides if the label is hard to spot. The model number identifies your complete chainsaw, not just the spark plug or another individual part. Enter it in the model number search to pull up the parts matched to your unit, including engine, fuel, cutting, and ignition parts. Matching the full model before ordering helps account for differences between similar Poulan saws and puts the correct options in front of you. That means fewer wrong orders and a faster repair.
