What is the popoff pressure for a stock 97 Monte Carlo 770?

Thanks

The pop off pressure should be 16 psi if using 2.0 needle and seat with
65g spring

Re: Carb popoff pressure

I thought I read somewhere it was 29 so I ended up using the bigger spring from the rebuild kit.

Is it ok to leave the larger spring with the pop off at 29 or should I change it to the smaller spring and get it back to 16?

Thanks for the help and great products!!
