Good afternoon, I have a mep003a generator that is recently started surging and wanna cut off. I see the governor arm keep moving up and down to adjust for the fuel. Any idea for me to troubleshoot or fix this problem? I've recently changed the fuel filter and air filter and oil changed along with filter. I have a video clip that I'll upload along with this post. Thank you for reading and helping also sorry if I've posted it in the wrong section.
