We are refering to actually watching the fluid,, how it discharges,, it must start to discharge from the nozzle the INSTANT you move the throttle,, it must be a strong, continuous shot of fuel for as long as you move the throttle..
Also after moving the throttle about a 1/2 to 1 inch, stop and hold.. wait 5 seconds,, it must instantly deliver fuel when you resume throttle movement,, any delays you SEE,, will be your hesitation.. Do it numerous times,, scrutinizing the flow,, somewhere there's a pause, splutter.. hope it helps.. really do..
