Check that the barb fitting for the regualtor isnt plugged with crap and same for the barb for the ecu or map sensor.
Sometimes you get a bit of fuel/oil mix sitting in the bottom of the tube to the ecu and this can play havoc with the ecu's mixture setting.

Also check that regulator is working. Connect up a syringe and pull a vacuum on it while the engine is running. Check fuel pressure before the reg.

Also dissconnect the primer wires from connector block on the side of the motor.

Have your injectors been cleaned and flowed? Could have flooding injectors?

Do you have a 56 lb black reg on a 39 lb gold regulated system ? Is your return line clogged or kinked ?
