I'm having a problem starting my brand-new Troy-Bilt Bronco 42 CA with a Briggs & Stratton engine. It was already assembled when I bought it but has never been started. It cranked a few times but never fired up, and then just started clicking. It's getting 12.4 volts. I saw yesterday's post about the Troy-Bilt 'Won't Turn Over or Click', but I'm afraid if I might void the warranty if I try the solenoid test as recommended in the post (and are the solenoids inside the starter in this model?) Is there anything else I can try before I have load this back in my truck and haul it back to where I bought it?
