Husqvarna 125L/2005-09 String Trimmer Parts FAQ
What is the Husqvarna 125L/2005-09 and what does the date code mean?
The Husqvarna 125L/2005-09 is a straight-shaft two-stroke gas string trimmer from Husqvarna’s 125L series. The /2005-09 identifies the production year and month, which can help identify the correct carburetor and fuel system configuration for older units when ordering parts.
Why does my Husqvarna 125L/2005-09 not start after off-season storage?
Hard starting after storage is almost always caused by carburetor varnish from ethanol-blend fuel sitting in the float bowl during warm months. Drain the float bowl before off-season storage to prevent this. As an older unit the diaphragm may also have hardened from years of fuel exposure.
How do I reload the trimmer head on the Husqvarna 125L/2005-09?
Press the retainer tabs on the bump knob to remove the spool. Wind new line in the direction shown by the arrow on the spool, thread the ends through the eyelets on the head housing, and snap the spool back into place.
Why does my older Husqvarna 125L run lean even after carburetor cleaning?
On an older 125L the carburetor diaphragm may have hardened from years of ethanol-blend fuel exposure. A hardened diaphragm cannot flex adequately to pump and meter fuel, and cleaning cannot restore it. Complete carburetor replacement is required.
