G'day guys, model 15R76A. Completely serviced. Pulled carby apart and cleaned etc. All orifices. New float and reset same correctly as per Joe Reeves article). Motor starts fine, runs a short time then sneezes and stalls. Try mixture screw and it wants to run too rich. Seems as if it is running right when first started and then something happens to make it lean off. Thinking maybe something still floating around inside causing a blockage (unlikely due to very thorough clean) or air being sucked in somewhere. Any other ideas?
