#1 Throttle By Pass Valve (s)

Post by mikebryan » Sun Nov 22, 2020 4:37 pm

My 1968 S1,5 ex USA OTS has the twin Stromberg 175 CD-2 carburetters, The front carb has a by pass valve with a vacuum port to the manifold, whereas the rear carb has no by pass valve, but instead a metal plate, held down by three pozi drive screws

My workshop manual indicates that a By pass valve is fitted to each carb. I am wondering if this plate on the rear carb is correct.

Thanks

Mike
