That 7.4 volts you claim is at the distributor puzzles me??????
With the points closed there should be near ZERO volts at the distributor and with them open it should be near full battery voltage which is like 8.4 volts!!!!!!!!!!
You say you have a resistor buttttttttt if its a 6 volt coil on an 8 volt system that ballast resistor (if sized correct) would be quite a bit less resistance then a regular ballast for a 6 volt coil on a 12 volt tractor..
All that aside possible causes or premature points burn up are: 1) Excess current (points and coil), it shouldnt be much over 4 amps if even that high, but if a lot more the points will burn quicker 2) A BAD OR INCORRECT SIZED OR NOT GROUNDED OR MISWIRED OR POORLY GROUNDED CONDENSOR 3) Residue on points 4) Maybe a bad distributor shaft bushing/bearign and the gap is drifting all around
With a 6 volt coil and some sort of ballast on an 8 volt system I dont see excess crrent as the first problem so Id really be checking the condensor and of its wired correct and if its well grounded to the distributor as the cause of premature points burning
Since youre willing to try anythign Id start with a new condensor and insure its ground. Im curious about those voltage readings also. If theres 7.4 volts at the INPUT of the 6 volt coil (NOT the to distributor terminal) when the points are closed n conducting current that may creat a bit of excess current but not enough to quickly fry the points

Today's Featured Article - 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.
