32$ for turning a single screw is a little much
You sure it's not a torx bit you need- ike a T25?
If it's like an allen head, use something like a 2.5 mm hex drive socket
for $10 if you don't have a metric allen wrench set that goes that small. Or buy a metric allen wrench set that includes a 2.5mm and add it to your tool box.
Or hit up the local AutoZone (or whatever you have) and pick up a tool there like OEM brand carburetor adjusting tool p/n 25062
, about half the cost you saw earlier.
