Interesting. One guy is cutting, rolling, shaping & welding steel into a functional metal sculpture. The rest of us are pecking on keyboards. I can't wait to quit the rat race and be just like this Unknown Welder.
Richard S: hmmm, let's hope that he remembered to leave room for his clutch!
I'm a huge fan of Gordon Jennings' seminal book, Two Stroke Tuner's Handbook, especially Chap 4 on this exact topic. (That book was probably the best tip ever & came from guys on the old forum!) Forty-five years on, I'm sure not every sentence is perfect but at least now I feel like I more or less understand the principles. It's long out of print but the PDF can be downloaded from the web. (BTW, Jennings makes a few references to sources he had at McCulloch.)
As I recall, Gordon said that the distance from the piston to the midpoint of the converging cone is more important than the header length. (I have no way to know if he was correct.)
