Solid state coil 35135 8hp Weak spark

The strength of a magneto spark is directly proportional to the speed that the magnets pass the coils.
Ask any one who rides magneto powered motorcycles about this
So what looks like a pathetic weak spark at cranking speeds can be a blow you away spark at running speeds .
That is why B & S make the 3 point spark tester ( magneto strength tester ) and the sliding contact magneto strength tester was invented.
 
I have one. Don't really use it much. I think that is the vid that starts out with a small gap and then opens it up to 6mm with it running. I just grab my briggs tester. If it will jump the gap it will run the engine. Some folk say they can analyze the condition of a spark plug with an adjustable gap tester. For $2 i just put in a plug and leave the VooDoo plug analysis to others. There are as many myths and "internet facts" about spark plugs as there is about motor oil.
