I have a 08 525xc I can't get quad to start. If I get it a shot of starting fluid it will start and run as long as I keep throttle opened up if I let off it stalls checked TPS and it is where it has been, marked from KTM, I took micro switch out of throttle housing because I switched to Honda throttle cleaned it up thinking carb might of got dirt in it from last hare scramble yes also changed spark plug. Thanks for any help.
