rustypete,

Ok what you have not done is replace the diaphragms in the carby as they also will be damaged from the unleaded petrol.

The pulse primer is part of the carby which moves the pump diaphragm in the carby in order to such fuel from the tank but note that fuel should flow from the tank to the carby only a trickle.

Hope that this is of some help. cheers2
