First off, THANK YOU for the input. My truck is running 100% better now that choke is not on all the time. No more black smoke, running rough, etc.
Runs and idles SO MUCH BETTER.

HO455 - rod I'm referring to is the vertical rod from choke spring up to choke blade lever.

And yes I think I need to go back to the original rod as the new one is probably too long. Doesn't seem to have enough up/down movement.

1) Should the choke blade be completely closed when COLD or should there be a 1/8" or 1/4" opening or gap ??

2) is the choke blade held open by the pull off only or the choke spring rod or both ??

I apologize for being so dense on this but I'm learning a lot and I'm very happy that I am making progress on this problem (which I thought was
something way more expensive). Now I just need to dial it in (I think) with decent fast idle when cold and kick down nicely when warm.
