In that case, check the system voltage at medium rpm. If it's below 
13.5 V, replace the voltage regulator.

In spite of what people say, it's almost impossible to judge spark 
quality by eye. Basically you either have spark or you don't. The 
only good test is to use a timing light with an inductive pickup to 
verify that spark is actually passing thru the wire to the plug. If 
the spark doesn't jump the SP gap, then the light doesn't flash.

Also, the TVS is NOT the problem.
