Champion Inverter Generator No Start Troubleshooting 

The choke should be closed position once it's warm. Leaving it open for it to run means there is a problem. You didn't put it in economy mode to see if it ran ok?

followed your guidance and did half of it wrong and used my endodontic reamers to clean out and ready to throw the whole thing away but it now works ... after loss of sleep ... love ya a bunch ... keep up the good work ... my Chamption Inverter 2500 is humming away nicely ... very hard to believe it works now ... after a night of loss of sleep ... THANK YOU

You might want to check the spark arrestor, running rich as it was, it's probably plugged as well, nice job!
