wow, lower that down to 3 - 3.5 and start there. Drive it easy to see if the starting issues go away. If you find out then you dont have enough volume then you can go up slowly but might have to look at the fuel pump.
Pressure is one thing but high volume at a lower pressure might be the FP you need. The stock SE one might not be cutting the volume once knocked down to carb pressure. Did you swap that out yet or running a different one?
Cant believe what RB says here:
Fuel Pump - You will need to purchase and install a fuel pump that provides a 6 PSI delivery with a minimum 20 GPH rating - selection will depend largely on installation location. The stock fuel pump unit is designed to provide high pressure (40+ PSI) for a fuel injected intake and is not compatible with this carburetor application. It is NOT recommended that a fuel regulator be used to reduce the stock fuel pump pressure to 6 PSI- the stock pump will fail.
6 psi seems way too high! Are you still running the return? If so then maybe the 6psi is fine. On all the carbs I have used with out the return it seems like 3.5 was the max.
