I bought my O-360-A1A through Van's from Lycoming. After I got the timing straightened out it worked very well until the non-sensor mag failed after ~400 hours I bought one from a fellow in California and no more problems. When I was going through my original timing problems I dealt with an excellent Unison Customer Service Engineer. Then later when the mag failed that excellent customer service engineer was no longer in the loop and I was told the company was bought by GE. Now I see a fellow is advertizing his sensor mag for sale because of the high price now demanded by Champion. I'm very satisfied with my system but I am curious about who owns it now and the future expectations of company support.
