I obtained a used BME 100. It had a failed C&H ignition unit that I sent into C&H for repair.
The engine starts and runs quite well now but will produce a lot of RFI if I am not very careful to get a good fit on the spark plug leads to the spark plugs. Since I have to remove the plug leads to remove the cowl I am doing a lot of range checking with the engine running. With a PCM receiver this means a long walk every time the cowl is removed. I need the exercise but I am never sure the cap will remain in place throughout the flight.
When changing the spark plugs on my Ford I noticed they recommend putting a non conductive grease on the plugs when reinstalling them.
Anyone have a magic substance they put on a plug to help in this situation?
