Thought the cylinder chambers were 56cc on my head... they are 49 on the money. So my compression is now going to be 10.6:1, way too high for pump gas. So my question is... if I get a HG with a 50 crush, I can get down to around 9.9, which is doable.
Where can I source this gasket, what does it cost, and what's the highest compression I can run in a built 250 with a 4v carb and mikes head? Thanks so much, amigos
