How does one ascertain whether the magneto points are tungsten or platinum?
My KVFTT makes a great spark, engine starts easily, then after some 500-700 miles, progressively starts to misfire under load. Inspection reveals a growth on one contact & matching divot on the other as material transfers. A quick rasp with a points file to remove the growth, and all is sweetness & light again for another 5-700 miles.
I suspect tungsten points, but I am open to all suggestions????
