Hello,
I have the MTH Premier UP 1943 and I hear a strange noise coming from the engine. It sounds like a grinding sound, I can’t really describe it. I took off the shell and ran it around the layout without sound or smoke, and I did not see anything that would be causing the noise. I have a video of it running without sound with the noise. Does anyone know what it is and how to fix it? Thank you.
Ricky
