I am tracking down a bogging problem, and while checking the accelerator pump I noticed that the primaries put out fuel and the accel pump give a health squirt but the secondary are as dry as a bone. the butterfly valve on the secondaries are fully opening also. I just need to know if this is normal.

Thank You

 

They are "VACUUM" operated. You do not see the secondaries spraying unless you mod them to mechanical.

 

yes. I did the mechanical mod three or four years ago. sorry!

 

AFAIK the accelerator pump only squirts into the primaries; nothing to do with whether or not the secondaries are vacuum operated, mechanical or atomic powered.
