Re: The new member with first engine

When burning and rotate the flywheel, i see piston move a little, i feel the hot volume is quite small. I intend to change the bigger hot cylinder, with bigger diameter about 32-35mm, of course diameter of displacer has to follow, everything not change. Is it ok?
