Husqvarna weed trimmer carb adjustment

The hi/low carb adjustment on this model has the screws that are knurled on the outside with no slots or provisions to use some sort of screwdriver... Short of having to go buy the tool , I'm wondering if anyone has come up with a sort of contraption that will grasp these screws to adjust?? Was told to try a bic pen using just the body but this doesn't seem to grasp the screws.
 
Lol so what I wound up doing was remove the carb , then taped off both sides to keep minimal debris out , then took a small sanding disk and brought the height of the surrounding aluminum down to where it was flush with the screws.
Then took a small zip disc and carefully put a slot in each screw head.. Gave the carb a quick spurt of cleaner and installed.
Worked great if anyone encounters this problem down the road.
 
Just go on line and buy a HIPA set of drivers. You get like eight of them for under 20 bucks. Looks like the future for all of us backyard tinker type. I have a new chainsaw with that crap. New tool time !!
 
I have had a 12 piece "Made in the USA" set of HIPA drivers for years. I got them just before dealers were banned from selling or even loaning them to people.

Besides the basic 8 I have a 22 spline, Flat tip, Triangle, and a Torx.

A lot of people have told me that the cheap Chinese made ones sold on the internet are hit and miss as to them working or not.

You need a small flat tip Jewelers screw driver to adjust most Echo equipment except their chainsaws which take a regular small flat tip driver..

I quit Husqvarna when I walked into the local dealer and found that he had replaced the parts guy with his college educated son. Told him I needed a gear head for a 326 RJX, Even gave him the part number. He came back and said that he could not get one to fit a trimmer, But could get one that would fit a 372 X-Torq chainsaw. I walked out. Went to Echo and have not looked back..
 
FYI: If it ever goes to a dealer after that, He may refuse to work on it because the 'emission controls' have been tampered with. Its your baby from then on.
If the EPA ever catches a dealer working on a carburetor that has been modified like that the fine can put him out of business.
 
Understood , I don't take things back to the dealer generally speaking.... So for me in this case the juice was worth the squeeze.. I am however going to do a bit of searching for these proper tools.. I had no idea there were even different sizes lol. Thanks a bunch for all the info
 
I have some 1/4 od plastic tubing that fits on tight enough to take the needle completely out, then I took a dremel with a small cutting wheel and put a screwdriver slot in it.
 
Forgot to mention, we got a new Stihl leaf blower last week and the carb is adjustable with a flat screwdriver and there are instructions in the owner's manual how to do it! Surprised me! Why the change?
 
I found a small piece of brass tubing. Heated pretty well with a propane torch. Pushed over the screw and presto a tool was born. Probably a piece of copper tubing would do the same, might not even need to heat it. HTH Tom
 
I bought a new Poulan Pro chainsaw to leave at a camp and not lose sleep if it got stolen. It was not usable the way it was adjusted when new. I also got a new Weedeater-brand brushcutter and it too would barely run. I think it is a crime that new stuff gets sold like this with no easy way to adjust. I bought an 8 piece kit on Ebay for $17 and it has been great. Now - I have two new machines that actually run like new.

Some people use red crimp-type electrical but-connectors to grip the splined screws on some chainsaws.
