Just because you have a new set of distributor points doesn't mean they will fire.

I was having trouble getting the points in my Farmall Super C to fire. The tractor had been parked for around 20 years. I had a new set of points still in the package that I purchased quite a while ago. I installed the new points and condenser. I cleaned all wiring connections, checked for grounds, checked for power, changed the coil, etc. and still no spark at the points. I finally sanded the new points and problem solved. I guess the points had corroded a little while in the package.

Usually a wipe with lacquer thinner will solve problem when new .

It is common to have to clean/burnish the contacts of new point sets, right from a parts store. Likely oxidizing due to slightly different materials used to make them now and they don't turn stock over as fast as they did years ago. Other methods besides Lacquer thinner are to rub clean brown paper, card stock, between the contacts. Even a folded-up dollar bill can work.
