Breathing new life into the 318 in the Scamp!

Lost .5cc in the decking. Gained it back after chamfering the edges of the chamber. It's right back to where it was after I checked them all after the work.

I think I'm just going to bolt this thing together, now. The edges, especially by the valve opennings are a lot smoother, now with the modification I made. Should help with flame and a little with everything else.

I finally found a better dynamic calculator that allows me to put altitude numbers in. It's right at 8.9 or so, static. Dynamic comes in right at 8.4, static at sea level is somewhere at 9.7:1, so I don't think I need any more volume from these ports to get it into mid-grade. The chamfering was more to get rid of the nasty edges by the valves cleaned up.

Got the oil prime shaft ready for tomorrow. Stoked.
