The air cleaner box interior was surprisingly clean.

The throttle was also in good condition.
There’s some dirt buildup, but the piston operation is excellent.
We replaced the fluid.
I wanted to go one more notch, but I’ll hold off on pushing it further. This is a vacuum-operated carburetor, and adjustment is quite tedious…
If the chrome piston rusts, light cleaning without damaging the seals is sufficient. Over-polishing only thins the chrome plating and makes it rust more easily.
If it’s severe, disassembly and replacement of the seals and piston strike a good balance in terms of both time and effectiveness.
After that, a test ride and we’re done.
