584901401 Carburetor with Air Filter Tune-up Kits Fits Husqvarna 525L 525LS 525LST 525ES 325HE3 325HE4 525RXT

I have a mowing business and only use Husqvarna 525L’s for my weedeaters. After 3-4 years of extremely heavy use the trimmers get downgraded to brush cutter status (remove the trimmer head, replace with brush cutter head). My current one that I use for brush cutting wouldn’t stay running. After many years of use I went ahead and replaced the spark plug, and the fuel and air filter – still had issues. Got this carb – install took less than 20 minutes – now it runs like it did 3-4 years ago. Extremely pleased.
