I was given a 199? moto 4 350. It had been in storage under a roof for a couple of years. I got it running again, jump starting it, and adding fuel. It will Idle fine for several minutes but when I try to give it some throttle, it sputters and dies(sometimes backfiring). What would be a good next step to getting this ATV on the trails? What could be causing the backfiring. Also it is slow to start if that helps. backfiring multiple times on starting before finally running.
