I recently had a problem with my left magneto, the engine was running rought.  I took it to the local magneto repair station.  Had it returned and reinstulated it in the plane, repair shop said that it checked out.  I then pulled the right magneto off thinking that I may have pulled the wrong magneto off in the first place.  I took the right magneto to the repair station and was told that it checked out.  I replaced the right magneto started the plane on "both" and did a magneto check--left magneto the engine bounced all over the place and the right check the engine stopped.  I called the Laser Electronic company--purchased by Slick and I was told that the only similarly with the Slick magneto and Laser system is the Slick housing.  Also, I was told that there are only "two" locations that are authorized to work on the Laser Electronic systems--one in California, and one in British Columbia, Canada.  I sent both magnetos to Pro Aero Engines Inc. in B.C..  Received them back within a week, put them in the plane, started the plane and did my meg checks--they did a fantastic repair on both mags.  The total bill for both companies was $1800.00.  A word of warning--electronic magnetos take special electronic equipment to reset to the proper angle.  Ask the repair station how many electronic systems they have worked on and ask to see the test equipment--if they say a magneto is a magneto, there is no difference--run with your magnetos.  The only good point is that my magnetos were due for their 5 year inspection.
