Hi Samurai
If the baseplate isn’t moving round enough then something else is wrong. Maybe the points aren’t the right ones. Do they match the old ones exactly? Are you sure your trying to line up the correct marks? The timing mark is the one before TDC.
I never use a strobe. I always do the timing with a bulb and get it spot on that way.
If you wish I can explain how to do it that way.
