Well that makes sense now. So in your opinion, I don't even really need it? That's all I've been doing till now is like you, kill it with low throttle . While I have your attention, where do you get your plugs for this engine? I've been looking for the NGK CM6 but can't find it. Not even on tower.small engine shop?are there any other brands that are good?i know every one says the DLE plug ain't even good for a spare, but I have 8 to 10 flights on mine with no issue. I still don't really trust it though after reading what every one else has been saying.thanks a lot for the answers. Steve.
