My first guess would be something keeping a reed valve open, as the piston comes back up the bore, causing blow back. The reed valves, if the engine is equipped with them, are mounted between the carbs and the cylinders. how did you notice this? Is there an airbox, or air filters on the carbs? Lack of filters could have allowed something down the airways, and lodged into a reed, holding it open. just my guess...... Ed |
