Concur with Andy, get a good spark first, then clean the carb thoroughly and fit a new diaphragm. Have fitted pattern ones and have had no problem with them. If the ignition is a points type, its not the best design. I get to them by using an air chisel with a point fitted and put it on the crankshaft end. A put a prybar behind the flywheel, give the chisel a buzz whilst GENTLY putting pressure on the flywheel. If the combined points condenser, or the coil is duff. I would personally replace it with a transistorized module. Its a dead easy swap and the spark is much stronger. These small engines have a similar rev range and power delivery, so do not think swapping the original for another type will make too much difference to the machine’s operation. A good idea to fit a toothed belt to replace the original tyres.
