Hi, Playing with lawnmowers is part of my job so here we go. To make sure however about what you have before you take a look at the air cooling housing. The big black cab you took of to get at the ignition. There is a series of numbers stamped in normally a row just above the spark plug or on older models at the side of the exhaust. These indicate the model and type of the engine as well as the fabrication number. If you can give me these I will have a look at the micro film, so I know what we are talking about, and see if I can find a manual for the carburettor. Which is usually a standard type but relies heavily on healthy membranes.
