I have a converted-to-gas SuperTigre 3200 that has a different ignition on it. My buddy says he got it from someone named Crabil?. It is a homemade looking thing covered with heat-shrink. Has a hole in the heat-shrink to access a potentiometer. Also has a separate coil for the plug. It is made for the little 1/4x32 plugs. My question is: Where do you set the magnet pickup switch? The bracket is plastic and it has fatigued and broken. I'm guessing the switch will be at TDC, and the spark is set with the pot, but I would like confirmation from some of the more experienced forum members(Iwon't say "older" ;-) ) who may have run into this. TIA
