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.

Today's Featured Article -
Oil Bath Air Filters - by Chris Pratt. Some of us grew up thinking that an air filter was a paper thing that allowed air to pass while trapping dirt particles of a particles of a certain size. What a surprise to open up your first old tractor's air filter case and find a can that appears to be filled with the scrap metal swept from around a machine shop metal lathe. To top that off, you have a cup with oil in it ("why would you want to lubricate your carburetor?"). On closer examination (and some reading in a AC D-14 service manual), I found out that this is a pretty ingenious method of cleaning the air in the tractor's intake tract.
