Magnum 330 dies as soon as you touch the throttle. Clean carb new gas new plug starts right up and idles great but dies as soon As I barley touch the throttle. ETC is not touching, verified this. The boot is old and has some cracking it but is not causing a high idle. The bike dies when I spray brake cleaner around the boot. Doesn’t it normally idle high? Tried turning the idle up and it dies as well. Pull choke and it dies. Loosened screw on bottom of carb and fuel is flowing.
