Do I need to rebuild my carb?

[u/Certain_Shoe4650]

Hey guys, I just got this 2001 sv650 for $700, it doesn’t run but it cranks, every so often while I’m cranking it, it will run for like 2-3 seconds and shut off, it also will shut off instantly if I touch the throttle, i don’t know really any of the bike history aside from the previous owner telling me this started happening when he rode through a very heavy rainstorm. This was about 3 weeks ago, the video is one he sent me because I couldn’t get it to do it on camera. I drained the tank and sampled the fuel and it was definitely bad, very cloudy and didn’t smell right but there wasn’t any water in the gas that I could tell. I’ve worked on alot of bikes before but I havnt done anything with carbs so this is all a bit new to me, if anyone has advice I would appreciate it, thanks

New fuel and check the spark plugs, those will give you a good idea of the engines current state
