got a fcr 39mm carb that has no squirt from ap jet. had the bottom of the carb of and cleaned all jets but the pathway through the carb to the little jet seems blocked. i have filled the tube with petrol and carb cleaner to soak but still blocked, i have blown compressed air down the tube but no air comes out. how else can i clean the jet. the hole is too sml and facing the wrong way to get jet cleaners down it.
