Fed, not looking for the thread spec.but looking for the hole diameter that feeds the extra fuel to the main channel after it pass's the power valve. Also know as the "pvrc".

Appreciate your quick response.... "happy new year"... Norm

Howdy Norm,

For the 650 annular discharge venturi two barrel carb,
PVCR hole diameters = 0.057" +/- 0.001"

Metering body number 34R-7023A, original main jet = 22R-40-82

Might check further with Braswell as he did a lot of those back in the day.

Regards,
Dissident
