If you changed ignition points in the last 100 miles or so, you'll think the rubbing block must be made of Chinesium these days because the distributor cam will wear it down quickly, even if you lube the distributor cam. The points gap with close down as the rubbing block wears down. You'll have to check the points gap once in a while in the first 100 miles and adjust them according to how much more the block has worn away. It will reach a point where the block won't wear anymore and then it won't be necessary to regap the points. This just happened to me last Friday in less than 40 miles on a fresh set of original style points.
