FuzzayD Posted May 29, 2013 Share Posted May 29, 2013 I have a Weber 32/36 downdraft and i want to delete the power bypass circuit diaphragm on the side if that's what it is most race prepped Webers seem to have it removed but I'm not sure what exactly needs to be done like block a hole or something bypass something has any one done this?

FuzzayD Posted May 31, 2013 Author Share Posted May 31, 2013 This is the area where what i think is some power bypass diaphram bolts on Quote Link to comment Share on other sites More sharing options...
azzurro Posted May 31, 2013 Share Posted May 31, 2013 i think that is the accellerator pump and so you dont want to remove it (for normal driving anyway). is that a DGAV? Quote Link to comment Share on other sites More sharing options...
FuzzayD Posted June 2, 2013 Author Share Posted June 2, 2013 its the water choke one the accelerator pump is on the other side and actuated by a cam on the primary throttle shaft this thing is connected to a vaccum line just under the secondary butterfly so is like an additional accelerator pump? seems like vaccum will pull the diaphram against a spring until throttle is opened then the spring must force fuel into something. I've just seen on some cars that run these in formula ford have these missing Quote Link to comment Share on other sites More sharing options...
