Hello VAF!
During my engine run-up this past weekend, I discovered the Light Speed side (Left) of engine was running rough. I noticed a corresponding #1 and #2 cylinder temps started to drop while I was on the left side. I couldn't leave it there long because the RPM was decaying pretty rapidly. On the Right Side, the engine was running smooth and normal. The engine time was just over 1000 hours and I was planning on replacing the plugs anyway, so I went ahead and changed all of the left side plugs. When I ran it tonight to see if it fixed the problem, the engine was actually running worse than before on the left side and still running smooth on the right side. I also noticed the engine ran slightly rough while in both. I'm wondering if I have a timing problem with my light speed ignition? If so, what tools and other parts will I need to trouble shoot? Is there previously posted trouble shooting advice?
The plane was running fine two weeks ago.
Thank you for your help!
