Thanks Bob... Bugman... I'm certainly looking forward to it myself!
It's a fair way off. He has a major development job to do on the Poly yet, but it's possible that he might look at gasflowing the flathead at the same time if I can get what's needed ready in time.
I would think that plasticine in the chambers could be one way of experimenting for improvement. Certainly it would be a way of checking if filling the chamber for compression might affect flow.
