S40 won't start
 

Hello, new member here. So here is my dilemma. I purchased a 2005 S40 recently. The bike was running rough when I got it, but it ran. It supposedly only needed a muffler, which I replaced. I did the basics, changed the plug, drained and replaced the fuel and changed the fuel filter. It started but would stall out. So I had the carb rebuilt. Floats adjusted. Same thing. I replaced the fuel petcock. Got a shock from the coil wire when checking spark so I replaced that. I am at my wits end. Its trying to start but it's not getting something. I'm hoping that maybe it is out of adjustment with the carb, I don't know. Any input would be appreciated.
