quote FrankR:

That was my “Final Word”. After I practically wrote a text book on the subject. I stand by my word in both cases.

That’s perfectly fine, FrankR – and you may well be entirely correct – at least in terms of the OBM hardware discussed on this site, if not more generally.

What I offered was an anecdote, nothing else, and should not be taken as some sort of unequivocal declaration of a universal truth. To be clear, I don’t place very much faith in anecdotes, and neither should you or anyone else for that matter.. they are subject to innumerable biases, errors and outright manipulations.

Also, are you doing those moped tests with the muffler installed? Just as having an outboard in the water, there would be a small amount of back pressure. I’m not concerned enough or interested in pursuing that topic.

I can’t recall whether or not any of the mufflers were removed for these tests, other than in the case of my machine, which did have a muffler. Either way, it doesn’t matter as IMO the resultant course of action should be the same in any case. That is, since we know some engines are susceptible to this issue, we hold the throttle at WOT in all cases simply because it’s one more variable that can easily be eliminated.
