My gx160 powers a water pump. Has sat unused for 9 months. Engine starts well on choke but stops after literally a second or two. Refuses to start again within 2 minutes. Will not start without choke. Plug clean and spark good. Have cleaned out carb. Fuel supply to bulb underneath carb is good. Have cleaned the holes in the small brass unit that pushes down into the top of the carb. My suspicion is fuel starvation, but I don't know where else to look for a blockage. Have replaced oil in lower reservoir to max limit. Any ideas would be most welcome. Thanks, Tony
Remove and clean the jet set pilot (black plug on the top of the carbi) replace the o ring if squashed or worn. Clean the small bowl under the fuel stop cock valve, flush the fuel tank, blow the fuel supply line with compressed air and fill up with fresh fuel.
Is the air filter dirty? With the bowl as the lowest part of the fuel system, any dirt or water will wind up here. Turn off the fuel valve, or drain the gas tank, then place a rag under the bowl to catch the gas that will run out. Loosen the "nut" that holds the bowl on, and after the gas has stopped draining remove the nut and bowl, but do not let the float swing all the way down! Wipe out the bowl. The "nut" usually contains 1 or 2 very small passages, soak in (or spray with) carb cleaner and use a wire bread-tie or other soft wire to poke out the holes. Blow out with compressed air, if available. Put the bowl back on and try to start it. If it still will not start, it needs a good soaking and a rebuild kit.

If inlet valve is breaking always wat is d major problem
IF ENGINE IS EQUIPPED WITH NEEDLE
VALVE ON CARB TO REGULATE MIXTURE,
TRY ADJUSTING. PATIENCE, TRIAL AND ERROR WITH VALVE ADJUSTMENT WILL
PROBABLY GET YOU THERE.
