Hello, I need to know how to replace the wires on a 5hp briggs horizontal shaft engine. It came off a snowblower with the wires all brittle and it isnít getting any spark. The plug is OK and so is the coil so I think itís the wires. If you could, please tell me where I need to run the new wires to in order to have a way for it to get spark and run, and than kill it. I have tried many combinations but still not a tickle when I pull the cord. Thanks, brian
