So I've noticed lately that my husqavarna string trimmer bogs down a lot under full throttle. I pulled the plug and its white and ashy. Definitely too lean on the high end.

So I grab a screwdriver to adjust the high needle....

Nope...

Its got those stupid splined adjustment screws. I'm not taking a 100 buck trimmer to an engine shop just to open the needle 1/8 of a turn.

Before I take this whole thing apart and use a needle nose pliers to try and pull the screw to slot them with a dremel... Anyone know where you can actually buy the stupid adjustment tool for these things???
 
Maybe a piece of tubing? You should be so lucky that's it's fuel line size…or perhaps a piece of shrink tubing that's not shrunk.
 
I used a chunk of copper tubing soft enough to form to the splines but stiff enough to turn the screw.

Try Radio shack, some of the Electronic tools are splined.
