You guys had me worried, I only have one gasser it is a Giant Big Stick powered by a DLE 30, I set it up about 2 - 3 yrs ago and had forgotten how I did it. I felt compelled to go out to the garage and see. I found I had used some kind of nylon/carbon linkage. On returning to my study I checked the DLE manual (not the one that came with the engine but a more extensive one that I downloaded) and it clearly states "Be sure to use a non metallic linkage". Just thought I'd pass this on.
