yes

try rigging the air valve open. the secondary rods will be up but no fuel should flow through until air moves past the secondary throttle plates. they don't open until around 1/2 (?) throttle.

it will have a significant bog but should eventually pick up and move.

G,H and I are part of the 'priming' circuit, providing initial fueling to the secondaries before the main discharge takes over.

 

Not sure how much I helped myself, that priming circuit works.
Unhooking the linkage to the air valve, no change.
Zip tying it open, definite bog, it would kind of recover back not really better.
Pull the rods out completely, still bogged, still not right.

if any of those scenarios helped, it wasn’t noticeable, there might be a step in there where the doors are forced open, then adjusting those rods out more but not all the way is where it needs to be but I couldn’t really test that.

I think I’m going to need to figure out a way to watch the oxygen sensor while it’s doing it to see if it’s lean or rich.
