All Plugs Fouling on Right Bank

Ok #1
See that choke pull off on the right lower portion of the picture? It should be pulling the choke blade open.
Is there vac to that diaphragm, is it pulling on the linkage.
When it's cold and the choke coil is strong, the choke pull off can only pull it out so much, as the choke coil warms(eng warms up) the coil gets weaker and the choke pull off, pulls it fully open. like your finger is doing in the 2nt picture.
If the eng is running, in that 2nt picture, the choke pull of is NOT working.
You are still running rich, because you choke is not working properly.(not opening up fully)

Once you get your choke pull off to work, there is instructions on how to set that up as well.
