Can someone explain the proper procedures to remove, clean, and re-install the carburetor inlet screen.
I thought this info was posted here but can't find it!

Access to the screen is through the big brass hex nut 90 deg offset from the fuel inlet. Cut safety wire and unscrew. The screen is right there. No torque specified for reinstallation, just tight with no leak.

Thanks Much!

There is a copper washer under the plug. It might make sense to anneal it while it is out.
