Poulan Pro string trimmers are workhorses in the yard, and when they quit — whether it's a clogged carburetor, a snapped trimmer line, or a worn-out spool — Repair Clinic has the OEM parts to get you back to trimming. We carry genuine Poulan Pro replacement parts for carburetors, primer bulbs, fuel lines, spark plugs, and trimmer heads across their full range of models.
A jammed trimmer head or cracked primer bulb doesn't mean the trimmer is done. Most Poulan Pro repairs are straightforward and affordable — often under $30. Find your model number on the equipment nameplate, and we'll match you with the exact OEM parts you need.

The most common reason is a clogged carburetor, especially if the trimmer sat for more than a month. Ethanol in fuel gums up the carburetor jets and needle seat. A carburetor rebuild kit (or full carburetor replacement) usually solves it. If the engine cranks but won't fire, check the spark plug for fouling or corrosion. If it won't crank at all, the primer bulb may be cracked and won't build fuel pressure.
The model number is stamped or printed on a nameplate attached to the shaft or fuel tank of your trimmer. It typically starts with "PPT" or "PPCT" followed by a series of numbers. Enter this exact model number into the search box at Repair Clinic to see all compatible parts for your trimmer. If you can't locate the nameplate, describe your trimmer (gas vs. Electric, shaft type, engine size) and we can help you narrow it down.
A carburetor rebuild kit includes gaskets, seals, and internal parts to clean and restore your existing carburetor. It's the cheaper option and works well for light ethanol damage. A full carburetor replacement is faster if the carburetor is severely damaged or if the rebuild kit doesn't solve the problem. Poulan Pro carburetors are model-specific, so verify your model number before ordering.
Trimmer line is a consumable — replace it whenever it runs out or breaks. Load the correct diameter (usually.065" for Poulan Pro) and length for your head to avoid feeding problems. The trimmer head itself lasts years, but if the spool cracks, won't rotate, or line won't feed, an OEM replacement head is the fix. Bump heads (line advances automatically) are standard on most Poulan Pro models and are very reliable.

Poulan Pro typically prints the model number on a nameplate attached to the trimmer's shaft or fuel tank. Check both areas carefully, and copy the letters, numbers, and any type or suffix information exactly as shown. Once you have it, punch it into the search bar to sort the catalog down to parts for your specific trimmer model. The model number applies to the complete unit, so it helps narrow every related parts category, from fuel-system parts to ignition, starter, engine, and trimmer-head parts.
