hey, i'm using a 255 walbro, the motor is still flooding without the EMS, FMU, and VAFC, my shop is suggesting me to get the stock pump as well, but i never had these issues before i replaced the head, and the fuel system should be independant from the head replacement.

The head i replaced with right now was used for about 10k miles, SS valves, but theres is a significant amount of valve tapping. Will a valve adjustment help my flooding issue?
