Used running mulching mower craftsman with bag. It only wants to start when starting fluid is sprayed into the air filter. Runs fine after starting. And will restart fine without starting fluid.
Had new oil, air filter, and spark plug this year. New pull start and gas cap. Carb cleaned this year. 6.5hp Briggs Stratton engine
Model: 917.388850
