Cloud - thanks for the detailed info. My choke never moves as the generator is trying to start. Maskes further sense as the genrator actually does "start" but it sputters for 5 to 10 seconds and slowly dies as not getting the air it needs (choke never opens). The choke also does not return if I force it open, it just stays open but does seem to very slowly drift to near closed as it runs with time.
Kpack - It is model 5.5HGJAB-1038C Spec C. A Service manual would be awesome.
nugget - Thanks for the part number. Looked on web and for others it is the dome looking part with blue grommet(?)on the end. Looks like easy repalcement, true? I can see this diaphram part move the black lever it conencts to shown in the first pic but it never results in it opening the choke (just moves within the semi circle slotted piece on the other end). Maybe the diaphram is cracked so it still moves just cant generate any force to move the spring? Did yours move at all? Just wanting to make sure its not the bimetallic spring/linkage ... dont know if anyone can tell from the pics ... wish I would have taken a video now before putting in storage hundred miles away.
Thanks everyone for the continued input!
