Youre right, it might?? foul less BUT ONLY FOR A WHILE UNTIL THE POINTS BURNED UP (thats if you increase the current draw). Points can switch around 4 amps (and still have a decent lifespan) or so but if you increase the coil current by using a high energy coil that draws more amps, they will burn up quicker. Thats why its best to use an electronic switch which can handle more amps then points were designed for and when its matched with a high energy high voltage coil and a wider plug gap is used THEN YOU GET THE REAL ADVANTAGE and get all the bang for the buck an elec switch and high energy coil have to offer....... Sure one can widen the plug gap with a stock coil and perhaps gain some improvement, but the laws of physics and conservation of energy apply and theres only a fixed finite amount of energy stored in the coil during its conduction cycle and thats alllllllll (less heat losses) the energy available for discharge across the plug gap. Therefore, if you widen the plug gap increrasing the firing voltage, then either current or the arc duration time decreases since the energy discharged is volts x amps x time..
Dont get me wrong THERES NO HARM in running a high voltage coil if it doesnt draw much more current then the points were designed to switch although it still fires at the same voltage as the stock coil if compression and gap remains the same. Its just that if you use coils that draw more amps the points will burn up prematurely

Today's Featured Article - Earthmaster Project Progress Just a little update on my Earthmaster......it's back from the dead! I pulled the head, and soaked the stuck valves with mystery oil overnight, re-installed the head, and bingo, the compression returned. But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
