bob in CT wrote:How about the condenser? If your points are transferring material from one side to the other, it is the condenser. Point quality suffered when production shifted to China because of tungsten quality. Impurities in the metal can leave an oxide on the surface. A friend of mine that used to work for the phone company gave me a telco diamond points file. What a great tool to have. I installed a Pertonix in a three of my tractors, but I just had to pull one out of my 1950 project tractor when I couldn't start it for the first time. Put the points in and it started right up. Still a fan, though, as the timing stays right on and never changes with rubbing block wear.


A condenser change with points is good. Saving a marked good one after removal ,just in case....
Hmmm. Since you mentioned rubbing block wear. Rob: hows your rubbing block and what drives it look like?

The IH manuals that I've read also give the same info about using sandpaper as Jim related in his posts. Can't remember which ones but it's there. Auto Parts sells the points file for a couple dollars. I've used sandpaper in the past, (prefer an emery board over sandpaper) clean the area as good as possible afterwards. I try to keep a points file on hand.

The first set of point were worn right out but the second and third were new. I'm thinking the new coil doesn't have a resistor in it. And when i clean the points with sandpaper i always blow them off with air and then wipe them off with a clean cloth. Never had a problem this way.

Well i put the original coil back in because the new one didn't have a resistor in it. I noticed the spark at the point was real strong looking compared to the original coil. Hopefully that fixes the problem. I'm knocking on wood right now, i sure hope this fixes it.

You can add a resistor inline between the coil and the distributor and be OK.
