I GOT A NEW SET OF POINTS AND CONDENSERS FOR THIS MOTOR.SIERRA 18-5002.NO MATER WHAT I DO I CANT GET THEM ADJUSTED TO CLOSER THAN O25.anybody had this issue before.Should the point wiper be adjacent to the flywheel key or top on the flywheel taper.

Is the cam screw bottomed out?-----And you can use the timing marks on the flywheel ( yes there are two ) and the vertical lines on the magplate to set points with a meter.----Gets you the STRONGEST spark.----Tutorials on U-TUBE for this " best method " that I have used since about 1968 !

the actual gap isn't all that critical. the timing of the openning is critical
see video. .020 is a ballpark using the high point of the cam

just adjust the gap openning " time" per video
