Thermo quad 6138s ?

On some other Thermos it is. The accelerator pump arrangement
is somewhat different on most later carbs.
I looked at a few pictures like the ones I have and it looks like the celerator pump rod is different... On the one I have compared to the ones online.I was curious.I have a few that look like they have the correct rod but i'm not sure... As well as the choke pull off and linkages and things.
