This can be true. Especially if one is making a rational arguement and the participants are trying to reach a common goal - such as better understanding of some specific phenomenon. Thats not the case the case here, and I can name several others as well, who insist there is only one way, their way. If they seem successful, then perhaps they are right, but when they are discredited, then we know that what they are preaching is not so.
I'll disagree with you on that. The message is wrong. If it was presented as "it depends" then it would be a different message.
Yup. And we do what we can to make our stuff work. Not many of us have the luxury to do another engine build.
Yes. More so we do not have a comparison with a mechanical advance curve set up that would mechanically allow the same initial thereby allowing the use of timed port strictly for leaner mixes. I'm not actually suggesting he do that now. Its a lot of work for someone who is satisfied with the current arrangement.
I've seen a few people learn from some of the threads about timing, but can't recall any which devolved into pseudo-theoretical arguements changed any minds.
