What effect does throttle valve boost spring tension have on shifting,etc (#346 in the CK book) I have seen different size springs on the valve, (some on the inside some on the outside)throttle #302 in the CK book. Am not sure what spring I need there in a BRF-VB. Only one I have is a stiff one that goes on the outside of the valve. Am not talking about the big spring #304.Am I making any sense
it's been a long day.
Thanks.

Thanks.
