Engine math is very cool......but sorta over my head.

All I've used is trail and error. Lots of videoed cuts to compare timing numbers and so forth. To get the gains I've found in most cases has taken more error than many would believe. I have some big crates with tested jugs that didn't impress. :(

Well, don't let Joe fool you, he knows what he is doing and has an engineering background he uses to prove things he looks into. He IS the one that came up with the T/A program for chainsaws that I spoke to you about. You would have a ball talking to him! However, to Randy's point, Edison said 'invention is 1% inspiration and 99% perspiration'. I was once told that you could tell if a guy who ports 2-strokes was any good by the number of trashed jugs on his wall!

IMO everything an engine does or is capable of is based on math. There are some folks out there who have an inherent understanding of the math no matter if they they learned it in some sort of school or through trial and error. It is obvious to me that you are one of those folks. The fact that you were able to determine what the designers were after and improve on it proves it beyond doubt.

That is why I sent an extra jug with the Solo 665 in case one needs to end up in one of those crates!

Looks like I should learn to listen more. It might save me a few bucks in extra cylinders. :)

I think you listen plenty good! So why do you think that the Solo 665s will be something special as quoted elsewhere?

Cool, take your time, I'm in no hurry! It will be interesting to see if the timing numbers are close to the 7900/681 as you suspected. Would sure be nice if you could get the kind of gains you usually get like those that Joe commented on. If that is how it turns out, I am sure the rest of them will be headed your way.

I suppose that we could do that if it will help you out.
