Hi All, I am working on the Briggs 16 hp cast iron single 326437 it was running fine was adjusting the carb when suddenly it started running intermittently like the ignition switch was being turned on / off checked the spark and it was cutting in and out removed the points cover and checked the points and found the they were barely opening tried to adjust them now have no spark and have very little plunger movement what could have happened?? Is it possible to remove the plunger without braking it and not having to open the engine?

The cast iron block engine's flywheels must be re-polarized to use the magnetron ignition , I put a magnetron on my ss15 for a while and never could get it to run correctly. I though it was the carb. When I went and restored it I put a new set of points and condenser in it and it runs great. I have put magnetrons on aluminum block engines with great results.
