Hi
Does the S3 petrol have a non return valve in the fuel line? I'm having trouble starting, spent hours pumping the priming lever yesterday and managed to finally get a dribble of fuel up to the carb, it's a brand new pump with a good suction if you put a finger over the inlet, I checked for leaks and it all looks good,
Anyway I went back to it today and it was bone dry again, surely it shouldn't have all leaked back to the tank?
Any ideas? I'm going to take the inlet off again and blow the fuel line out with the compressor but there was plenty of clean fuel in the sedimenter bowl
