Chuddy 117, I just went through the same thing with my IR 125 compressor, new wires, thought coil was bad, (faulty ignition switch), good spark, gas to the carb. still wouldn't start, checked for stuck valves (happened before, ok this time) pulled carb apart, full of crud, rebuilt carb. still no start. drained gas tank removed and cleaned out, put new gas in and success, started right up. Combination of dirty carb & bad gas. Good luck.
