Thermo quad 6138s ?

[flathead31coupe]

Can someone tell me if the choke rod and pieces, as well as the fuel pump rod from other tq carburetors are interchangeable... also, does anyone have a picture of a 6138s factory carburetor from both sides.So I can tell what's missing on mine.Thanks.

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.

Only a couple different Accelerator Pump rods.

If it looks right = it probably is the right one.

The later TQs have a different casting on the airhorn for the acc pump lever. The casting sticks out further towards the front & the lever used for these is also different. Distance from the pivot to the hole where the 'S' link goes is longer. I believe the connecting rod is also different. The pump plungers are the SAME.
