Hey guys, I'm officially stuck. I have an 80cc motor that seems almost like it could be getting to much fuel i don't really know. I have checked the fuel filter. I have replaced the spark plug. I have Re sealed all the gaskets. I hit a point and it'll act like it's bogging down. If i hit a slight down hill it'll kick over and pick up speed. Could this be a muffler problem? I have done everything i can find/research wise. Any help will be greatly appreciated.
