Okay, we all know that engine leaning on the ground is mega important to avoid deposit build up when running 100LL. How aggressive is aggressive?
I have heard many people say "lean until it's rough and then just rich enough to smooth it out". This leads me to a question.
When I lean my engine on the ground this is what it looks like in order as I bring the mixture back:
1. engine rpm increases
2. RPM maxes. At throttle back all the way engine rpm will be up around 950-1000 RPM (These numbers are off, correct ones are in post 12)
3. I can continue to lean without much changing for a little bit
4. The engine starts to develop a ticking sound and EGT on #3 starts rapidly going up compared to the others
5. RPM starts dropping and engine starts running rough
So here are my questions. What the heck is that ticking sound coming from? Should I richen enough to make it past the ticking sound or just rich enough to avoid the rough running?
