Okay so im a honda guy and im new to 2 strokes and polaris in general. I just bought my brother a 97 Explorer 400 4x4, when i was looking at it it was a little hard to start but once it did it ran good so i assumed maybe it needed a carb cleaning. Well got it home rode it for a little bit and all of a sudden it died on him and wouldnt start, checked reeds, one looked a little burnt and was bent up a little, didnt think it was enough to make it not run. Have good start and im getting fuel coming back through carb air filter side. It had a huge back fire through intake that, anybody know what my issue is? If what im saying isnt making sense just tell me and ill try and explain it better
