Yes but those look professional. Mine resembles a cb shop we had closeby in an rv at a truck stop.he had a swrs (as he called it) meter cresent wrench,wore out allen wrenches and his trusty golden screwdriver.not sure if he had a soldering iron .might been like tool time tim with a decent tool , dangerous
actually i got 2 of em.supposed to be with every stihl gas powered product sold new.bought new stihl chain saw n weedeater.salesman said we dont give em away as a rule cause people mess up carbs easy.he knows i never touch a little carb like they have but use those drivers on other thingsNot professional just cheap Chinese fine tuning screwdrivers so you can turn every trim-pot or coil slug regardless of the type of head it has.
Modern 2 cycle equipment has to meet EPA standards. In order to do this, they run lean and way too hot. They generally need to be richened slightly from the factory settings because the extra fuel is part of the cooling. Your altitude and even the outside temperature effect this too. Tuning carburators is a lost art. Most new equipment has a crude form of electronic fuel injection. It's only a matter of time before people figure out how to hack them.

yes,they set them when you buy them. I can set 1 but i trade them off every 2 years.so why bother them? I set my tractors when they need it usually winter to summer,richer in winterModern 2 cycle equipment has to meet EPA standards. In order to do this, they run lean and way too hot.

I loaned one of my chainsaws to a neighbor and he tweaked the carb to get maximum RPM and it came back with burnt piston.
To adjust a two stroke properly turn it out and when you get max RPM turn it a little more until it starts to stutter. The two stokes use the air/fuel mix as a coolant. It needs to be a little rich on fuel.
You can make more horsepower on just about any engine running it lean, but you melt parts, detonate, or seize the engine.[/QUOT
There is that perfect sweet spot never above or below it
