   Hello,

   I have a 1969 427 with the 3 two barrel intake.  I am seeking opinions on the current spring color that is being used in other 3X2 setups.

   I currently have the yellow springs in the diaphragms of the front and rear carbs.

   With Regards,
   Mike C.

The only multi carb setup I ever delt with was on a 1953 ford flathead motor.
The only thing I would say if that spring is in there and running ok. leave well enough alone..............jack

Helllo, I see this is an old post can look to see what springs I have on mine 68 3x2 400HP. They kick in around 4000RPM and will go only under a load pretty much 3/4 to full throttle.  What exactly is your goal ? Are you trying to open them up faster, less, or more ?  What I can see is your return is on the opposite side as mine and you have one spring there, but you are asking about the spring in the diaphragm pods. Also there may be a difference between 400 and 435HP too.
