I have a BN7 MkII with HS4's and when I pull the choke knob all the way
out I get travel on the cam to increase the rpm's but not enough travel
to pull the jet tubes down thus making the mixture more rich. With the
knob fully in, the fast idle adjustment screws are backed off just clear
of the cam. What am I doing wrong that's not allowing the jet tubes to
pull down with the choke fully out? Any thoughts on how I can correct
this? The other question is how (if it's at all possible) can I install
choke return springs on my carbs?
