Hello, I have a 80cc CDH Power with less than 200 miles. I'm still using the 16:1 mixture, however recently it began losing power specially when going uphill and the other day it completely left me stranded. I had already cleaned the carb a couple of days before that. Today after changing the spark plug and praying, it started again, however it is still making ugly noises and losing power. This video's quality is really horrible, but the important thing is the sound of the engine, can anyone please give me any advice?
