While trying to figure out why in the **** my 80cc is running like garbage, i took the carb and intake off just to peak at the rings. when the piston is at the bottom of its stroke i wasnt able to see the top of the piston, and into the combustion chamber like i can looking in through the exhaust port. so the fuel is actually going under the piston, is that normal? sorry if this is a stupid question i couldnt find anything while searching. i did notice another port in the combustion chamber, so i was hoping that the fuel goes under the piston then gets pushed up through the 3rd port?
