I got my car started today, fmax and Jim Wolf 4 bar. When i start it i can only get 14 psi of fuel pressure. I tried adjusting the Sx fuel reg. up and down and no change. I am running the walbro 255 hp fuel pump. I cant see or smell any leaks. I hear the pump running when i turn the key to prime. I am out of ideas. Also the adjuster bolt will only go so far down now it gets really stiff to the point where i cant turn it anymore in certain spots.(its not cross-threaded) Anyone got any ideas????? I am going to change the fuel filter tomorrow
