Greetings - Have 2005 Mule 610 that will no longer start. Had previous ignition problem where mule would not turn off. Found broken wire on coil and replaced coil with new one. Also cleaned the carburetor and jets, cleaned the rotor and stator and reset the valves all per specs in the shop manual. Starter motor is also as new. After all this, I did get the mule to start up once or twice after putting gas in the spark plug hole. New plug also...now nothing happens except the occasional backfire. Checked regulator etc. all check OK, all new relays, fuel and pump are good...at a loss as what to do next. Kawasaki in Panama is worthless and would charge a fortune if sending what might be a mechanic to the island I live on...better to try myself. Any advice on what I'm doing wrong or where to start over. Ran fine before, not now. Thanks, Thijs
