I am new to this hobby. Well, i jumped right in after reading a few articles and took the engine out of my Exceed Hyperspeed car. It is a .16 engine and i ported the sleeve on it but going back together im unsure on which way to face the piston as there is a hole cut in it on one side. It can either face the exhaust port or one of the intake ports. Also what would be a good starting point for the low and high speed adjustments on the carb? Thanks
