Can a tiny epoxy spot on a spinner cause vibration
I have a new da-50 on an EF YAK 88".
At idle, there is very noticable vibration. There is a tiny amount of epoxy on a CF spinner (which I spilled by mistake).
Does this small amount of epoxy on the spinner cause vibration?
What about the spark plug? After braking in the engine, spark plug was not changed. I just changed it and haven't tried the engine yet. Could this be a reason for the vibration?
TIA
