Of all the safety wire, lock nuts ,lock washers, and castle nuts on aircraft and they bolt the carb on with almost nothing but spring washers and a torque wrench. Add some RED locktite to those if you chose not to drill and safety wire. Ask how I know.

Red if you never plan on ever taking it apart without a lot of heat
