What effect does lowering the intake port have on the performance of a saw? I understand it would increase the duration the intake port is open. It would allow for more air/fuel mix to fill the crankcase. By lowering the intake one is also advancing the intake timing. Does lowering the intake have a similar effect as raising the exhaust port. Raising the exhaust increases engine rpm, while sacrificing some torque. Lowering the exhaust increases torque, while sacrificing engine rpm.
