I just took another look.
Primary fuel bowl #134-103
Secondary bowl #134-102
Which are center-hung fuel bowls. (That's a GOOD thing.)
The primary bowl is listed as possibly being on a MARINE carb?
In any case ... both bowls will have accelerator pumps attached to the bottom of BOTH bowls if it's actually a "double-pumper"
Edit: Sorry, I was typing this while you posted a response to my last one.
My aplogies ... not trying to be argumentative.
