Two cylinder Mitsubishi engine Has it just started this? Black smoke is too much fuel or too little air. Is fuel quality ok, no gas has been added to diesel tank? Valves been adjusted?

Ask Your Own Small Engine Question
Customer reply replied 9 months ago
It ran out of fuel, so fresh fuel was added, valves have not been adjusted since it was running fine before it ran out of fuel
Technician: Curtis B., Technician replied 9 months ago

You bleed both injectors and both are firing? Check the fuel supply from the tank , to the filter, checking the fitting at the filter, which is where any debris from tank would gather, if it is too big to go into the filter.

It has good fuel flow at all of the bleed screws
Technician: Curtis B., Technician replied 9 months ago

It ran out of fuel, so any debris in tank, could have accumulated at the first fitting at the filter, don't overlook, what can be problem. Smoke can be from inadequate fuel flow too the injection pump.

I took all the fuel lines off and blew them out. Checked fuel coming out of fuel tank and it was clean. Put the fuel system back together blead fuel filter,injector pump and line to injectors .
Technician: Curtis B., Technician replied 9 months ago

Result? Still runs and dies? Run test line direct to he injection pump from a raised container. If no change, injector pump is bad.
