Why does my LIFAN Power USA Engine have insufficient power?
If your LIFAN Power USA Engine has insufficient power, it could be due to several reasons. The valve clearance might be too large or too small, requiring adjustment. Also, a contaminated air filter foam can cause this issue; try cleaning or replacing it. Finally, check for carbon deposits blocking the exhaust port and muffler, and remove any you find.
How to start a LIFAN Power USA Engine that is difficult to start?
If you're having trouble starting your LIFAN Power USA Engine, there are a few things to check. First, make sure the choke valve is closed. If it's not, close it. Next, ensure there's enough fuel in the fuel tank; if not, fill it up. Lastly, there might not be fuel in the carburetor, so press the prime pump of the carburetor several times.
What to do if LIFAN Power USA Engine fails to operate at high speed?
If your LIFAN Power USA Engine won't operate at high speed after starting, examine the spark plug for issues like too large clearance, carbon deposit, breakdown, or electric leakage; adjust the clearance, clean the carbon, or replace the spark plug. Also, ensure the choke valve and accelerator are fully opened. If not, fully open the choke valve and fully open the accelerator.
