That is just a warning required by EPA. I am not that obedient!
People have tuned the OEM PZ30 successfully for years.
The airscrew is deliberately covered (another EPA requirement), but it is just a flathead screw on my Youall PZ30 smoothbore clone. And yes, it is adjustable!
The smoothbore carb that Templars come with is probably a better carburetor, but it comes with the same EPA required warning.
The OEM carb on my Storm was also sealed up, but that didn't stop me from opening it, rejetting it, and shimming the needle. Runs great.
