Default Nut thread dia/pitch Eng Mtg Bolt?


On my very first test run with my new 2-stroke, 66cc China Girl engine, I lost two of the four nuts that secure the engine to the frame. Can someone tell me what the thread pitch is for the studs that go into the engine at the mounting positions, the diameter appears to be 6 mm. I would like to obtain a tap and make my own nuts with safety wiring provisions in them to cure the problem. Thanks guys.
