Fuel Mixture Instructions For 2 Stroke Engine Scooters

Fuel mix ratio is 32:1
If you want to mix it richer use 25:1
If you want to mix it leaner use 40:1.

Note* 32:1 is a good safe mixture, it's lean enough that spark plug fouling will be minimal but rich enough that the engine is sufficiently lubricated and will not suffer any harm. 40:1 and leaner will provide more power but less lubrication. Any ash less 2 stroke oil brand is acceptable for use in these 2 stroke engines. Examples are: Pennzoil, Honda, Lawnboy. All auto parts stores and Walmart Stores offer these in the oil section.
Failure to mix oil with your gasoline will result in engine seizure within 30 seconds. 4 ounces of oil to 1 gallon of gasoline / petrol is = to 32:1

Looks like the fuel cap is behind the seat, so most likely the fuel tank is under the seat.

A manual is available here:

You most likely have oil spilled on the clutch. OR, the carb needs to be opened by 1/4 of a turn on the set screw on the carb.

No, there is only one gas tank on a scooter of that type. You ALWAYS use premium gas, correct? Also there is a small hole in the gas tank cap. Air must be able to enter this hole. Make sure it isn't clogged and air can enter. NEVER let your scooter run out of gas if you can help it. Make sure the gas filter is clean and installed correctly (follow the flow arrows printed on it). Hope this helps!

the mixture ratio is 50 parts gas to 1 part oil. Use only a good quailty stroke oil, never use motor oil

i have fire and new cdi ran find for 2 days but hard to start now it will not start

check the hoses that put gas on the carburator, and also the pump. Check the spark plug, better take it off and clean it and check the gap.

That problem has happened to me to and i just ajusted the needle on the side becuase it was too rich or the breather on the gas tank sometimes that gets fratured and the gas fumes cant get out right
