Then, with only half the return spring pressure, you don't have to put your foot up on the dash to pull the choke cable,
IMO, if it's that stiff with both chokes hooked up, there is something else wrong. I pulled the same cable every day for almost 20 years, still worked fine. I grip the knob between index & middle finger, then prop my thumb on the dash. Then a twist of the wrist pulls the choke out, and another locks it.
I've found that it's common for people to try stretching the spring between the jet glands, which makes the choke hard to operate (and also gives the jets a tendency to stick down, causing overly rich mixture even with the knob all the way in). Then some will shorten the return spring, to get the jet to come up, which makes the choke even stiffer.
Also worth noting that all those pivots in the choke linkage are supposed to be loosy-goosy. Substituting bolts for the pins, and pulling them up tight, is a mistake.
Pressing on the throttle while pulling the choke will also make it a bit easier.
Oh yeah, the jets are supposed to be smooth and shiny. Many aftermarket jets aren't smooth, and need to be polished before installation.
