Specs for 7029529 power piston spring
« on: October 30, 2023, 12:46:14 PM »
Can anyone tell me the following specs for the OEM 7029529 power piston spring?

1. Free length,
2. Outside diameter
3. Wire diameter
4. Number of free coils

This one was used in a lot of 70s Pontiac carbs (and some Chevy too).  Trying to sort through a bunch of my used PP springs and figure out which ones are OE to which carbs.  Thanks in advance!!!
