I want to know if anyone knows which way the arrow on top of the piston should point to?? up pointing toward the carb intake or pointing down toward the exhaust ? i was always thought upwards but ; i"m not sure. Its now pointing down toward the exhaust. The first or top ring gap is on the intake exposure and the bottom ring gap is on the exhaust exposure (gaps are pined) .
THANKS .Charles
