i think my excavator is getting too much fuel. when I turn up the throttle the RPMs will go all the way to where they should be but if I put a load on the machine it will blow a huge amount of black smoke out of the exhaust. I think the previous owner turned up the fuel injection pump to try to get more power out of it and is flooding the machine. Does anybody know how to adjust the pump? or what else it could be? thanks
