Hello everyone. I'm in the process of replacing a 98 model briggs single model# 311707 with an older 94 briggs opposed twin model#400707 and need help with the wiring. The engine being replaced has the two wires (red and black) coming from under the flywheel..stator?? and one black wire coming from the armature. The replacement engine has two wires (black and white) coming from under the flywheel and one yellow "kill" wire. My question is how to spice these together? I think the black wire coming from the armature of the "old" engine will connect to the yellow wire, but what about the white and black coming from the "new" engine?? How do I connect them to the red and black of the harness??
