Is there any alternative? I don't have one and I'm trying to adjust my weedeater...I can't fit any of my needle nose in there...what else can I try?

A screwdriver?
What "exactly" do you need to do? most adjustments can be done with either a screw driver or an allen wrench, i've never needed anything more. Do you have any pictures?

So far i've been able to do Mikuni, edelbrock, Holly, and other carbs with basic hand tools, maybe the occasional extension to get into a hard spot.

Sounds like you have a carb with the hex head needles. The best solution is to buy a driver, or find a socket that will fit it.

If you can find another model of the same carb with Phillips head needles, you may be able to replace them.

If it is a splined adjustment, you are not allowed to buy the screw driver legally by EPA guidelines. Anyone caught selling you that tool can be fined ~$3500 per screw driver. This is straight from the Husqvarna group as well as MTD.

Yes its splined but that doesn't make any sense? Why not?

you can get by with a crimp on electrical end if it is the splined one use a blue one held with needle nose push it on and turn slow

Is it a Walbro carburetor with the High/Low needle valves you are referring to?

because the EPA can only go after the law abiding repair shops/dealers....some private buyers have been contacted, offered to pay the fine, or face prosecution.

here is a link FYI,

Thanks for the link...its pretty interesting seems crazy to me but interesting none the less..I think I'll still buy one but thanks for the warning.

If you clean the jets and passages the engine should run fine in spec.

IF you have a John Deere dealer nearby, you might check and see if they will let you drop the carb in their ultra sonic cleaner....it works VERY well and does not damage all the cheap plastic things that conventional cleaners do.

I paid a half hour labor at mine for them to do my X300 carb (surging at idle and mid rpms) and it works better than new, now. Their tech suggested doing this every couple of years or 100 hours which ever comes first.

Okay, thanks. There are a lot of tricks if you "can't" buy the splined socket (or the "proper" one), you can usually get one that is the same but not "official" and have zero problems. Never seen a spline on a weed-whacker either, kinda odd. Is it a new one or special edition? i'm curious now

Consumer model string trimmer Walbro knock off carbs are so cheap as to be almost free. Check E-bay/Sr. Bezos, etc. they often come with fuel and air filters, fuel line, gaskets and a spark plug. All at a price less than a few minutes worth of labor.
If I can't get them clean on first try I order new ones from now on.
As for the spline screw the plastic bit from a electrical connector already mentioned sort of works, if the screw isn't too tight.
OR:
Sr. Bezos must be losing $38,489 on every order.

I was working on my Husqaverna and Stihl Chainsaws and bought this set. The 21 tooth spline tool fit both but the outside diameter of the tool was a little big for the Stihl. I am going to grind it down.

I got one of those super cheap nutdriver type small carburetor adjustment sets with the small spline, single-d, double-d, PAC-man… drives from Amazon years ogo. For the few times that I have had to use it, it has been great.

I do not believe that the set would stand up to everyday use. But, I am referring to a set that was priced under $2 per tool.
