Poulan Pro String Trimmer Spark Plug Parts

Poulan Pro String Trimmer Spark Plug Parts

A fouled or worn spark plug is one of the easiest string trimmer fixes — and one of the most overlooked. If your Poulan Pro trimmer won't start, runs rough, or dies under load, the spark plug is the first thing to check. Most Poulan Pro models use a standard plug that costs just a few dollars but makes all the difference.

OEM spark plugs are matched to your engine's fuel mixture and ignition timing. Using the correct plug type — typically a Champion or similar heat range — ensures reliable starts and smooth running year-round. Enter your Poulan Pro model number below to find the exact spark plug your trimmer needs.

• Won't start even after priming: fouled plug needs cleaning or replacement
• Runs rough or sputters under load: plug gap or heat range is off
• Hard start that improves when the plug is new: old plug is weak
• Black sooty deposits on the plug: rich fuel mixture; clean and reinstall or replace
• White crusty buildup on electrode: lean condition or wrong plug type

Poulan Pro String Trimmer Spark Plug Questions

What spark plug does my Poulan Pro string trimmer use?

Poulan Pro gas string trimmers most commonly use Champion RCJ7Y or RCJ8Y plugs, depending on the model year and engine displacement. The correct plug type is printed on your engine block or in the owner's manual. Always verify before ordering — using the wrong heat range can cause hard starts or engine damage. Enter your Poulan Pro model number on this page to confirm the exact plug your trimmer needs.

How often should I replace the spark plug in my Poulan Pro trimmer?

Replace the spark plug at the start of each season (spring for summer trimming) or every 100 operating hours, whichever comes first. If you store your trimmer for the winter with old fuel in the tank, a new plug in the spring helps clear out stale fuel residue. Many owners keep a spare plug in their trimmer bag — it's cheap insurance against mid-job failure.

Why is my Poulan Pro trimmer hard to start after sitting over winter?

Ethanol in gasoline breaks down over months of storage, leaving varnish and gum in the carburetor and on the spark plug electrodes. A new spark plug combined with a fresh fuel and carburetor cleaning will get your Poulan Pro running reliably again. If the plug fouls immediately after installation, the carburetor may need a rebuild kit or full replacement.

Can I clean and reuse a Poulan Pro spark plug instead of replacing it?

You can clean a plug with a soft brush or fine steel wool to remove light carbon or fuel deposits, then reinstall it as a temporary fix. However, OEM spark plugs are inexpensive — often less than $5 — and a new plug help ensure correct gap and heat range. For best performance, especially at the start of the season, replacement is the better choice than cleaning old plugs.

Poulan Pro String Trimmer Model Number: Where to Look

Poulan Pro places the model number on a label attached to the main housing near the engine, along the shaft, or around the handle area. Turn the trimmer off and check each label carefully for a combination of letters and numbers, separate from the serial number or engine information. Type that model number into the model number search to pull up the parts matched to your unit. The result filters Repair Clinic's full Poulan Pro string trimmer catalog, so you can choose compatible parts for the entire trimmer instead of guessing from appearance or part names. It is the quickest way to be sure the part fits before you order.
