Hello Folks,
Newbie here to this forum so bear with me. I have a 64 1/2 with the code "D" 289 and 4 barrel carburator. With the engine off and the throttle held open, the secondary actuator lever can then be manually moved. My question is, should there be fuel pumping into the secondary venturies when I do this like occurs on the primaries when manually moving the throttle actuator? I'm not totally convinced that my secondaries are opening and if they are, they are delivering fuel. I saw a suggestion on one forum to fix a piece of string or tape to the secondary actuator, go for a test drive, floor the throttle and see if the tape or string is pulled loose or broken. My secondaries are NOT pumping fuel onto the throttle plates (engine off) when manually moving the seconary actuator rod, but I don't know if they should be.
Thanks in advance for the help.
John
