This is my first post, so please direct me if I posted in the wrong area. I had trouble starting my LA130 riding mower, so replaced the battery. Still no start, so I ordered a replacement aftermarket ignition switch & just put it in. I unplugged a set of wires that were hanging in the way. When done, I plugged the wires into the ignition switch and plugged in the wires I had disconnected. Mower started right up, but now there's smoke coming out the front of the mower. Any suggestions what may have caused that? This mower never smoked before.
