We think oil for the engine of our Devap 2600 PSI 50 Gas-Powered Pressure Washer #DVH2600, Honda 5.0 EXH2425 was put in the wrong spot... in the unlabeled orange-cap opening, not the small grey "oil" cap on side near bottom. When started, ran momentarily, then brown (oil?) came out of nozzle, then stopped. Yikes! How do we get the oil out of where it was put...? Will need to first put oil in the correct place?

No, oil was NOT put in the gas cap nor engine. It was put in what I think is the pump oil port (not the engine oil). The orange cap is on the pump, next to a label that specifies the type and quantity of pump oil to be used and the recommended frequency of adding oil. We did put this type of oil here. So perhaps I was wrong that the oil needs to be removed.

The brown discharge from the nozzle when we attempted to begin spraying with water made us think that. After resting, subsequent attempts to restart the engine are not successful.
