1970 WT Qjet is 7040263.
Float bowl on this is 1970 RamAir M/T 7040273 with lots of mismatching parts on it.

Hopefully, pictures requested! I see a 19 or a 61 on the inlet boss. Guess it is a 19. Please LMK. Thanks!

19 is correct. Need to see this number inside the yellow marking.
Throttle plate looks ok, need to check the size of off-idle slots above the idle needle holes.

Thanks Kenth. I don't exactly understand the last request, "need to check the size of off-idle slots above the idle needle holes". Please explain a little more or show an example.

The off-idle ports/slots on a RamAir Qjet throttle plate are shorter than on a non-RamAir Qjet.
Shorter off-idle slots above the throttle blades at idle speeds equals richer idle mixture.

Did you check the fine stamped number within the yellow ring?
