How to troubleshoot if the diesel engine speed is too high?
Answer: The throttle control is out of balance. Check whether the speed regulating cylinder is normal and whether the air pipe and joints are leaking.

How to troubleshoot insufficient diesel engine power?
Answer: A :The fuel quality is too poor. Drain all the fuel and blow out the fuel pipe.
B: Air filter is clogged, check, clean or replace.
C:Air or fuel lines are leaking or throttling, tighten fittings and replace if necessary.
D: There is air in the fuel system to vent the fuel system.
E: The fuel pipe and fuel filter are clogged. Replace the fuel filter and blow out the fuel pipe.
