What is the gas to oil ratio fot a 1982 Yamaha PW50? Do you need to mix it manually or does it automatically mix together by putting straight gasoline in the gas tank and straight oil in the oil tank?

32:1 gas to oil mixture
32:1 mixture,easiest way to do it is get a cup that gives you gallons to ounces ratio on side and fill to correct level of oil and pour into gas can ..any bike shop carries or can get very cheap and simple for consistant mixture.
the safest mixture would be 32 to 1
i have ran 6ounces of 2 cycle oil to 1 gallon of gas
32:1 is standard fuel mixture for 2 stroke engines, you can use different ratios but this is the reccomended ratio by the manufacturer.
what is the oil gas mixture for a ysr50
The mixture ratio for Yamaha outboards is 50:1 gas/two stroke oil. That is approximately one pint of gasoline to a plastic coke bottle cap full of two stroke oil.
If not using oil injection, the 115 hp Yamaha outboard will require a 50:1 ratio.
with the newer semi/synthetic oils mix at about 32:1 to 40:1 anywhere between these two is a safe ratio.
it could be a few things. too rich of a gas mixture, bad carburator. those are prolly the most often problems, try changing your gas ratio.
