George just to help you and provide you with a bit of information, with ALL DUE RESPECT regarding your statement:

"Electronic ignition products a higher voltage spark."

FYI the voltage required to cause current to arc jump across the spark plug gap IS A FUNCTION OF THE GAP DISTANCE AND THE MEDIUM (fuel and compression) in which it occurs. Its (spark voltage) NOT based on if its an elec switch or mechanical points switching the coil current on and off........An electronic ignition alone (versus points) does NOT produce a higher voltage spark !!!!!!!!! GIVEN THE SAME CONDITIONS the firing voltage using an elec switch would be near the same as points

1) And that's the same REGARDLESS if an electronic ignition or mechanical contact points makes and breaks the coil current

2) An electronic ignition (same as points) DOES NOT produce a higher spark voltage then necessary to arc jump current across the plug gap.

3) REGARDLESS if points make and break the coil current orrrrrrrrr a solid state device given the same conditions (plug gap and fuel and compression) THE FIRING VOLTAGE IS APPROXIMATELY THE SAME

Typically in late model cars with elec ignitions versus old low compression tractors, the spark plug gap may be wider in which case the firing voltage must necessarily be higher BUT THAT'S NOT CAUSED BY ELEC IGNITION (even with points the firing voltage would have to be higher if the gap is wider) ITS CAUSED BY A WIDER PLUG GAP!!!

As an electrical engineer and past farmer and old tractor dealer HEY I LIKE THE OLD POINTS SYSTEM AS WELL AS OTHERS but its an engineering reality that the modern elec ignition systems SO LONG AS THEY ARE WORKING are superior to using a set of mechanical, ever burning, ever corroding, ever increasing resistance, bouncing, ringing points to make and break coil current................WELL DUH

NOTICE I'm NOT arguing or advocating points versus elec ignition, do as yall please I AM STATING WHAT I BELIEVE TO BE ENGINEERING FACTS

I'm NOT advising anyone to change over from points, when I used and bought and sold old tractors I didn't change them from
points to elec ignition

I like points in old tractors and use them BUT I WOULD NOT CHANGE MY NEW CAR BACK OVER TO POINTS. There can be advantages as well as disadvantages to BOTH so TO EACH THEIR OWN PREFERENCES

Hope this helps your understanding (Hey I'm with you, WE AGREE, I didn't change any of my old tractors over either)

Take care n be safe Good Neighbor
