That seems pretty official to me.

If your pilot screw isn't doing anything then I'd suspect something blocking the pilot circuit. Be sure to blow air backwards to try and dislodge any foreign matter that might have crept in.

cheers for the info

They wear out, too.

Some re-sleeve the bore.

I wonder if one could knurl the piston?

What plug you using? Wrong plug will foul too.
