There was a time when "WE" (the consumer) had the ability to not only rebuild small engine carburetors but to adjust/make changes in the jetting.
Those days are gone - and it is going to get worse!
As an example - my leaf blower was not running "at speed". I could tell it was not receiving the needed air/fuel ratio. But, the two adjustment needles were capped and surrounded by a cast metal shoulder to prohibit any user adjustment.
When you run into this you have three choices:
Use of a Dremmel tool with a small round diamond cutting blade and prying off metal caps covering the screws and then filing notches so a screwdriver would fit the screw caps gave me access to the adjustments. 1/2 turn of the high speed jet adjustment and all is once again fine.
This is our EPA and CARB at work. They do NOT want anyone beyond the factory to be able to work on or adjust a small engine carburetor. Jets are non-replaceable, access ports are sealed and even parts are unavailable. You either do it their way or throw it away.
The next step is to require engines to be built so they cannot be disassembled. Bolts that tear up the part when they are removed, special licensing for repair shops, requirements for labels showing certification numbers for rebuilt equipment. If they have their way (which they will) all of our small air cooled engines will be "throw away" items that are unserviceable.
This is no joke. It is all real. Hang on to your old stuff as it will be the only ones you can take apart and fix when they go awry.

When you run into this you have three choices:
- Throw the thing away and get another
- Spend more than it is worth on a new carburetor
- Hack into it, defeating the mechanism to prevent adjustment.
