The engine is a model 132232-4036-02 and has run fine on my pressure washer for a long time. It won't run now and I have checked the spark and compression which are fine and also cleaned out the fuel tank. Replaced spark plug, installed new filter and pre-filter and added new fuel. It sounds like it wants to run but it just won't start. I have added fuel to the carb and it still won't start. Any suggestions.
