You think this is my first rodeo? I see more DLE spark plugs in a month than you will ever see in your life and believe me when I tell you, there is no error in this user when it comes to spark plugs or tuning. Your single 20cc engine and one spark plug is not much of a sample size for one to make a definitive determination on the overallquality of any part of it. Stick around, do some reading in the DLE threads, start running some gas through your 20, don't carry a spare plug when you go to the field, you'll see.

....its not about the money.. obviously.
You're right, it's about reality.
