Yes, it's not good - if the oil injection is operational and the line is not connected, the engine will not be lubricated and will be damaged - if the oil injection has been removed and you are running premix, the port needs to be capped or it will be a vacuum leak resulting in hard or no starting without starting fluid - not capped also means it is running lean once starter and can result in engine damage even if running premix fuel/oil - if the oil line is laying somewhere on the engine and the engine is run, the engine will become covered in oil resulting in dripping when parked and smoking when running. The manual I sent you should help you figure this out.
Gets fuel and spark. Ran great then one day after kids rode it it just wouldn't start. Tried what I guess is new electric choke, no change. It is getting 3.5 volts from the harness but does nothing when I turn the motor over.
