Hi,
Does the Holley 50cc pump go on front primaries or rear secondary's...
My carb is a Holley 4778-2 double pumper.
Thanks,
Ed

Originally, neither. Where was it? Must have been added by somebody? 50cc pumps (and bigger pump cam, bigger pump arm, etc.) aren't usually necessary except in specific situations in need of nearly twice the amount of accelerator pump shot fuel... and not always, but if added usually added to the secondaries. Did you get the carburetor in pieces in a box, or ...? Has that one got the straight-leg and bell-shaped skirted boosters? The rarely seen 700 double pumper...
