RE: DLE Spark plug, wire & cap
I changed mine because it came loose on the first run breaking in 1 gal of gas, talked to someone else and they said the Plugs come loose caused a few deadstiks, talked to yet another person, and he said it was well documented on another RC website that the OEM DLE Plugs come loose, that the compression washers fail, that everyone changes them out for the NKG CM-6; that was evidence enough for me to do the same, I will say, the engine ran great with the DLE Plug, except it came loose.
