Not aware of any "tamper proof" motorcycle carbs, but just in case:

Daughter was given a Ryobi gas weed whacker. Initial problem was ethanol-rotted fuel lines and primer bulb.

Fixed that, cranked it up, test drove it, gave it to daughter a month or so ago.

Last week, she texts me that it'll start but won't run on anything less than full choke and then only for a couple of minutes (before, I assume, the plug fouls out...) Okey-dokey, running too lean (Thanks, EPA...) I'll adjust the carb which actually DOES have two adjustment screws.

Or not, they're just round shafts with a little V notch down one side. Googled that, turns out Stens makes a tool for that AND Deep Homo can get them ship-to-store.

$43 later I have a set of 11 "tamper proof" carb tools in various formats and sizes - female rectangle, female splined, half round and v-notch.

About a quarter turn on each adjustment and it starts and runs like a top.

So THERE, EPA, stick yer tamper-proof where the Sun don't shine! :cussing::laughing:
 
In a pinch some of those "tamper-proofs" can be gotten around with a little creative work with small thin wall tubing. Find a piece that will fit snug and then more or less crimp to let them grab enough to turn an adjuster screw.

I bought a set of those too. Turns out I only use a couple of them but wouldn’t be able to adjust the carbs on my Solo yard equipment without them.
