Today I decided to re-gap my plugs and curiously looked inside my cylinders to see what I could see.
I have only run 50 hrs on the engine and 35 flight hrs. The difference being obviously taxi time, preflight testing, and a very annoying RPM issue.
Now while I was poking about, I noticed a deposit on the top of the cylinder near the spark plug on two cylinders.
I guess I am wanting some feedback from people on this issue and is it worth getting concerned about or is it standard and completely normal.
NOTE: I have not flown this very hard and it has been quite RICH to date, however, looking at getting into some significant flights soon and more lean mixture is to follow.
Thanks in advance.
