I disconnected the tors at the brain. Do I need to cut and splice wires? It wouldnt start while it was connected. it starts but runs ruff while n gear. mostly the bottom end. when im in the woods it boggs and off the line. Im trying a few things w the carb but was woundering if that could cause that. It kinda sounds like it looses spark. Not really sure. By the way, What is a plug chop?
