I received the new 099 distributor for a B20B engine to replace the wrong dizzy. Cleaned it up, oiled the shaft area. new points, cap rotor. Started right up. I have the Dwell at 59 so I am good there. Problem is the the timing is fluctuating. I will set it at 12 and it will dropped down to 0 on its own. I will then set is back to 12 at it will race to 25. Does this indicate a breaker plate problem? It was holding timing at first and them I needed to adjust the points. When I go to loosen the points screw the plate pops a little. Also is does this distributor need the vacuum hooked up after the timing is correct?
