This morning I was doing some test at 8000 DA and after completion I felt a little (very little) serge, so with the runway in sight I decided to turn off my EI switch, then EI back on, then the Mag off then Mag back on and no problem. Thought I would do it again and look at my RPM to see the drop. Switched the EI off leaving the Mag on and KA--POW. It got my attention real fast. I turned the EI back on and all was well. Thought it would be best to land and check out things... I believe but cant verify my altitude may have been 6000', (but I know it was NOT any lower) full power and LEAN 50* rich of peak (at 8000 DA). Just did annual 2 weeks earlier and Mag and EI both checked out ok. Also cleaned top and bottom plugs and checked gap. Also cleaned and verified injectors were ok.
