RE: DLE 20.....very hard to start (80+ flips)
With regard to the suggestion that the Chinese engines come with hard rings that need to be replaced, I respectfully disagree. I talked to Valley View RC right after I got my first DLE20 and they told me that this had been fixed and no benefit would be realized by changing them out. It took only about 5 flips to start mine out of the box and with minor adjustments it ran fine. I think too many people read these forums and then go about changing things without first trying to use the engine. How much power does an engine need to have? For minor, and I mean minor, performance increases people seem to be going to extremes. This is a great little engine just as is for what it is.
cheers,
