I have a Simplicity Coronet Hydro 12.5 Kohler 34" deck. Has a starting issue I can't nail down. Frequently No Sparks situation and now it won't at all. I can get spark when removing the kill wire from magneto. What I'm wondering is to get the lawn mowed, can I remove that wire and just put in a toggle switch from ground to magneto without hurting engine? Wiring is a mess and already has the seat switch removed.
