Melv, you will find the float very very small on these machines also the fuel stop pin, inside the carb there should be 2 jets, as Tony Clean / Blow them through but do not use any wires, If you are a smoker blow the smoke through the jet, this unit is very small to handle and so are the internal components so be careful, spread them onto Aa A4 sheet of paper, another thing to check is the Electric stop + the cable for the accelerator, does it do it's job?
