I have this cast iron Metra 65 for my pyramid reed engine, and neither the piston or cylinder skirt have windows. Should I cut my own ala flatreed?
Problem is, for example, a flatreed has a cylinder skirt window that you copy onto the piston at Bdc. I dont know where to start with this one.
It would be a pretty mild build, so I'm wondering if this would even net me any gains. Thoughts?
