Ok. So killing a reed valve motor by using the choke at WOT is the problem? It sounded as though people were saying "Don't use the choke to kill a reed valve motor." PERIOD. I myself have never seen or heard of anybody killing an engine at WOT. I currently run an Evolution 58GX and a 45GX .... and always use the choke to kill them ... AT IDLE. My thinking went along the same lines as Ralph. How can it damage anything when used at idle which is the same as using the choke to prime/start? As a matter of fact, both of my Evolutions start better at a fast idle so the engine rpm during that choke/start sequence is higher than when I use the choke to kill it.

BTW - My Evolution/Horizon manuals do not mention the warning that was quoted from the MVVS manual.
