Hi guys,after i saw some old 100cc aircooled engines i’ve bite the bullet and got a parilla tt36 rotary engine which is in need of a piston and a hone and maybe some other tlc.Im thinking of running the engine occasionaly but keep it in one piece as much as possible,What piston to cylinder bore clearance and ring end gap is normally needed on these engines without having them seize easy?i believe that as they aircooled they need a bit more clearance than usual.Thanks
