I have a 0-20 gauge. Normal pressures on my engine are 1-2 lbs on tickover, topping out at about 7-8 lbs. The blockage gives 5-6 on tickover, 15-18 lbs at 40mph. Poking the jets through restores normal readings, sometimes for the rest of the journey, sometimes just for a mile or so. The engine is well up to temperature.
