Problem SOLVED.... NAPA VT6187 is a VOLTAGE REDUCER for accessories such as heater motors, that draw WAY MORE current than an ignition system, so, under the lower current draw of the ignition system, it will not drop the voltage nearly enough!!! NOW we know why you are burning points... the resistor you have is not even made to be used on the ignition system! What you need is an IGNITION BALLAST RESISTOR.... NAPA # ICR-13 or Standard Ignition # RU-10 They are rated @ about 1.77 Ohms to 1.87 Ohms.
Alternately:
NAPA # ICR-23 or Standard Ignition # RU-11 This is the Positive Temperture Coefficient ballast resistor for use in circuits without a "starting bypass". It's cold resistance is about .50 to .60 Ohm, and quickly rises to about 1.75 Ohms upon startup due to heating from the current flowing through it. This gives better starts on units without the bypass from the starter switch or solenoid, yet the resistance quickly rises for long point life, and to keep from overheating the coil.

History of the Cockshutt Tractor - by Danny Bowes (Dsl). The son of a very successful Toronto and Brantford, Ontario merchant, and himself quite an entreprenuer, James G. Cockshutt opened a business called the Brantford Plow Works in 1877. In 1882, the business was incorporated to become the Cockshutt Plow Company. Along with quality built equipment, expedious demand and expansion made Cockshutt Plow Works the leader in the tillage tools sector of the farm equipment industry by the 1920's.
