Motor wont idle good at all. Have rebuilt carbs, replaced fuel lines. replaced water seperator and inline fuel filter. Runs fine at all speeds except idle, it cuts off while trying to load onto trailer. Is the idle speed screw the big screw toward the throttle linkage on the powerhead? I have tried to adjust it but cant seem to get it right. Any help is appreciated.
