Completely, and utterly false, at least in regards to the DLE20.

Ask Jody if he'd loan you one so you can test the chit out of it. In short order you'll be tearing into it, trying to figure out how it does so great. All along the way you'll be scratching and shaking your head and saying things like I don't believe it/no freakin way and so on.

Read the various threads on the DLE20, here and over on F.L.Y.I.N.G. G.I.A.N.T.S. and you'll see they're becoming very knowledgable about the DLE20 {ignore the "search challenged" newb's}

At least for that engine, it now holds the prize for being the best all around overall value in the low end of gassers, a place the 30 used to claim. No novelty involved with the DLE20, it's holding it's own easily.

Not so certain regarding the same being said for the 15 in the same respects.......but it's dang close!
I'm reserving judgement on the yet to be released 9cc.

Too bad nobody has a dyno to test the DLE20 on. I believe a slew of us would love to know it's true H.P.
Mfg's claimed H.P./C.R. are too often an advertising scam and overall joke.
