Help with fuel / oil mix ratio
I'm new here with a new bike. I have a 2-stroke 80cc engine and was wondering what the ratio is for mixing. I searched and see posts with 16:1, 20:1...etc., but I'm not clear on what that exactly means. I've never had an engine where I had to mix the oil with the fuel.
The guy I bought the bike from told me 4.1oz of oil to 1 gallon of gas, does this sound correct? How does that translate, or does it, into the figures above?
