Throttle return spring

JasonNC

I am in the process. of replacing the twin H setup with a single carb unit.  The throttle return spring is missing.  Is there a particular spring that was used on the 55 or 56 262 or 306 engines that’s readily available.

In particular, Grim Greaser has a dual spring on his project engine that appears to be what is needed, but I don't see those in stock online with the usual car parts stores...

I'm not entirely sure where I picked up the spring... Gotta be one from the parts store performance section...  I did drill and tap the block next to the serial# for the anchor though.

Those springs are on most q-jet carbs from factory.  More than likely found at Summit or Speedway or local parts store universal stock displays.
