Has any one had this problem? Was plowing garden running fine ,sunk plow to deep and was in hard pull started blowing black smoke and stopped. I can get it to start but it will load up and stop. Acts like a gas engine with choke on. i have pulled air filter, changed fuel filter, drained fuel and put in fresh,it did this after sitting all winter but ran fine for about 1 hour before it did this.Acts like to much fuel or not getting air.Does not act like compression Pull release and spins easy release it and it hits compression and starts but then black smoke boils out and it dies. Thanks for any help can give on this,thanks
