Title: 48DRLA body bore internal diameter
Post by: 181 on February 29, 2012, 22:14:32 pm
By chance, because my carbs are mounted in the car which is 100 miles from me in winter storage.

What is the exact internal diameter of the body bore? Is it consistent all the way down? I´m specifically interested in the area, where auxiliary venturi sits against the body. Can somebody measure for me? Thank you, Jan

anybody? If somebody can measure for me an outside diameter of 48 DRLA venturi, that would be great!

I believe the Aux-Vent for 48 DRLAs is the same one as for 45s.

Hi,
not the same auxiliary vents between 48s and 45s , possible to made 45s aux-vents with 40s aux-vents  P/N 10078.1 (not the 12189) by removing a big part of the  ring
vents have the  same OD (42mm) on 45s and 40s
