    Electronic ignition + auto plugs + auto gas = problem solved.

      Speaking for the LSA, that is just another reason I am using a Corvair engine.

        OH--- and don't forget--- unless your cylinders have helicoils in the plug holes--- you should NEVER torque your plugs while the engine is hot. You should wait till its ambient
        air temp. (because aluminum looses much of its strength at just a few hundred degrees-- so you run the risk of stripping a threaded hole if you torque hot)
        Might be worth installing inserts when the engine is built just to ease that problem--- ??? Might also prevent blowing a plug out if you ever got something like detonation accidently---
        I have heard of the warbirds blowing plugs out of the holes--- but I dont know what transpires to allow it to hapen---- (maybe past torqueing while hot ?)
