Update: How the hell do people cut that 2499 gasket material???

So after I gave up cutting said material for a new head gasket, I put one of the engines back together, I cleaned the head surfaces and added a bit of the copper spray to the original gasket. Now I am measuring 90 psi compression which – according to my brilliant calculation above 😛 – is impossible.

I think this is time to just enjoy having nice compression, rather than trying to calibrate the compression tester 🙂 I also checked spark again, this time with that gap-type spark tester, I am getting 1/4 inch spark just fine. So now I will move onto actually trying to get fuel into that cylinder. (I already cleaned the carb.)
