The other week I was out running my revo in the dirt behind my house. It was running really good, then all of a sudden the trail of smoke started to disappear and it just shut off. I tried restarting it but nothing so I took it back to my house cleaned it all up and still nothing. I took everything apart I resealed my engine made sure my plug was good fuel is good but still nothing. I don't know if I burned up my engine or what, I'm just out of ideas so what do you guys think?
