I am replacing the Briggs 16 hps engine with a 23 hps Kawasaki FX730V engine. I did rewire the tractor removing the safety switches and key switch, just a push button start switch, 4 pin solenoid. This engine has a solenoid on the starter. How do I wire up the push button starter switch. My tractor is a utility build with a Doc Sprocket locked trans axle, 12" rear pulley and a 4" front pulley. The rear rims are 12" and the tires are 23-11.5x12's for now. I do plan to swap them out for 26-12x12's will use the tractor for backyard utility use. Pulling loads up a steep hill and adding ATV implements.
