Hi all just a quick one
I have a 90 with a 3.5 strom carb that ive just put in and the carbs seem to be getting starved of fuel as the plastic inline fuel filter sems to be never full and when at high RPM its dies away, so to me it's like its running on the fuel thats in the carbs.
i was thinking it could be either a week fuel pump or simply to smaller fuel pipe. so whay size should the pipe be? and could it be anythin else??
