1 Potential choke problem from k1100 throttle body swap Wed Mar 30, 2022 1:17 am

I just built up a set of throttle bodies using k1100 TBs with the TPS shaft switched and k100 throttle cable stuff carried over to new.
It now seems like the choke mechanism doesn't have enough engagement to open the valves much at all. Way less than the K1 I compared to.
Is this a known thing with the swap?
Also, I swapped another shaft (forget why) and on both TBs where I switched the shaft the butterflies sit the same, but different than the other 2 (which also look the same). The untouched ones seem to seal perfectly and the 2 I touched have a bit more space when I hold them to the light. I tried changing the position of butterflies but still the same distance. they are now set so that all have the 10 print facing the same direction. How important is this if I am balancing them anyway?
