With 2 x 0.55mm base gaskets (1.1mm stack) the piston still sits slightly above the exhaust port floor, but only just. (Crown is 75.9mm below top of cylinder, so 1.6mm above port floor)
With 2 x 0.55mm and 1 x 0.3mm base gaskets (1.4mm stack) the piston is flush with the exhaust port floor. (Actually its 1.2mm above port floor)
I attempted to measure squish with this stack however there was that much squish it didn't touch my 2.3mm solder at all
Wondering though if I'm better off just using the 1.1mm stack, would having 3 x gaskets just increase my chances of gasket failure, along with costing more each top end? Will the piston being that extra .3mm lower make that much difference?
