The manufacturers recommend replacement when the center electrode has worn to 1/2 of its original diameter. Or if it tests bad of course.
2. O-360-A1A with slick mags ... do they need a rebuild at 500 hours? or just do they need to be cleaned and retimed?
And following another thread on Superior Vantage engines...rvbuilder2002 said:......
The later model mags (4300 series is the most current) have a 500 hour inspection interval. Complete the inspection and replace any parts determined to need replacing, and you should be good to go for another 500 hours.

Superior has kindly published the Slick Magneto Maintenance Manual (not available on the Unison site......) here....
