So I am new to the Chevy Nova world and this site. I picked up a 62 Chevy Nova 400 hardtop. It has a 194 with a PG trans. The seller threw in an Offy dual carb intake with two Weber 32/36 Carbs. I have installed those items and am running into an issue where I start the car and immediately it floods with fuel pouring out of the tops of the carbs. All of the parts looked new, cant verify, but that is what the seller claims.
I have done the following to try to remediate the issue.
1. Installed a Mr. Gasket Fuel pressure regulator.
2. Tapped off the fuel line to the back carb to work with only one carb.
3. Adjusted the floats 40mm with needle contact 50mm open.
4. Checked for additional vacuum leaks.
So this seems to be a stuck needle or float issue. Would it all be feasible to set the floats to 45mm and 50mm or increment hoping this flooding issue will stop? Or is there something else one of you might have run into that I am missing. Any suggestions pertinent would be greatly helpful.
I have also been to the Redline Weber site many times and know what they suggest. None is helpful at the moment.
