I have an eMag which uses smaller spark plugs than normally used by my O-360 cylinders. As a result, an adapter is threaded into the cylinder, and the Small plug screws into the adapter. What is the torquing technique? I would think the adapter would be torqued to the same value as Lycoming specifies for standard plugs. Then, since the smaller plug has a smaller radius of threads, a lesser value of torque would be used to seat the plug into the adapter. Does any one know how this is actually done, or can direct me to documentation ?
