other side of the carby is the fuel line from the tank. Other side of the carby goes back to the tank, when you push the primer you should see fuel going back into the tank
Norm, the carby has 2 fuel lines, one is a 3.5mm line from the tank, the other side of the carby is a 2.5mm line which goes to the remote primer. The other side of the primer is a 3.5mm line which is the return line to the tank. I have proved that the primer is all good as it pumps fuel OK. Im am thinking that there is a check valve in the carby which seperates the pumping side of the carb to the metering side. Air is coming into the system from the metering side via the little hole in the covering plate of the metering diaphram. I have looked online to see if I can get a body assembly pump, which has thelittle pipe fitted for a remote primer or even a whole carb to replace it but they all seem to have the primer attached to the carb.
