Looking to replace a part for the ignition on my splitter. The cord wouldn't contract all the way, which I could manage. But later it lost all tension for start up. I took the three screws off hood, and a the metal coil inside immediately became a jumbled mess and I notice a white smallish plastic piece loose on the side. Anyone know what to do to repair? If not, which part I need to buy? On this picture, i think it's either # 84 or 85, both are $$$. Thanks!
