Points are easy. Clip a test wire from the wire leading from the point to ground and turn the crank slowly until it lights, then check and see if the mark is lined up with the F. The plate the points are on will have screws you loosen to turn the plate until the points close and the light lights right when the timing mark hits F. Points need dressed periodically, get some krokus cloth and use it to sort of flatten down the contacts and remove any corrosion, then spray out with contact cleaner. Points also need gapped. Get some feeler gauges and find out the spec for gapping And the process for adjustment. this is all considered routine maintenance meant to be done with each oil change. 70's technology sucks, there's a reason they use optical timing or trigger wheels now.
