Re: Base Gasket
I assume you mean that you have a .025" head gasket 1/4" is kind of thick. the base gasket on mine looks pretty thick like maybe .040" to .060" range but i haven't measured it. one trick to making a gasket is to coat either the crankcase opening or the bottom of the cylinder with anti seize or machinist blue or grease or something similar and then press the gasket material onto it. you should then be able to trace the grease on the gasket material with a razor blade.
