Husqvarna Forest & Garden 125l 18" Gas Trimmer - Answered Questions & Fixed issues

You can't - it's fixed.

May need to have the unit checked. Could be something as simple as a clogged muffler, air filter, fuel filter or engine wear or damage.

There is no serving this module, it is sealed. Make sure where it mounts is clean and smooth, set air gap to .012"

Husqvarna does not recommend repairing fuel tanks. This should be a replaced item due to safety.

Test the coil with a spark tester. Also, clean the area behind the coil where it mounts. There must be good contact (ground) for the coil to product spark.

Hi winipig1 the heads dont pull off they screw off. Spray some lube oil behind the head and it should free it. It will undo clockwise

The ratio is 40:1 the greater being petrol

Hi there. Firstly remove the end with the starter cord and make sure the fly wheel is opening when you pull the cord. If not lubricate it until it frees.If it is working then it could be just the carb gaskets need replacing or the worst case is that the piston is broke and may need sorting.

Have you put the head on properly, is the drive shaft engaged in the gear head properly? What condition is the clutch in.?

Its a husqvarna tuning screwdriver

You either have your idle set too high or your clutch is worn/stretched springs

Check the spacing gap between the ignition module and the flywheel.. this alters the timing of the machine

Possible air leaking into the system. Also check the fuel tank vent, could be creating a vaccum in the tank.

Im not sure if you can

Have the drive shaft and gear hed become separated? Check integrity of drive shaft.

Is it the 'bump feed' type.? just knock the head on the flood while strimming

If its 'running on' then you either have your idle set up too high or stretch clutch springs.

Hope this helps

Have you put the gear head on correctly.? Are the ends of the shafts pushed in far enough?

Most trimmers use a 40:1 ratio on fuel mixture. Check the gas tank on your trimmer, as some manufacturers label it as an imprint in the plastic tank itself.

Hope this helps,
