Hello.I have mounted a very freeflow fuelfilter and when I fired up the pressure hold a steady 6.4psi.I took it for a spin and all of a suddent pressure is only 4.3psi,drove it for a while and gave full throttle,it went back to 6.4psi.The pressure continued to act like this all the time.
Could the needles in the carb be stucking and leaking?
Or what could it be?
Thank´s Gresse
