SOURCE: 2 stroke engine smokes. how do you adjust the fuel/oil mixture?

The thing with two strokes is that they smoke a bit under normal operation, and they smoke like mad if they haven't really been run for a period of time, I would advise you to run it for a while and see if that helps.

You should not need to adjust the mixture settings at all.


Hope this helps

Are you adding oil to the gas? (32/1 = 4 ounces per gallon)
Do you still have spark? Install a new stock spark plug.
Clean the carb, but follow these steps >

Remove the carburetor from the engine.
Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Remove the two screws on the outside throat of the carb and spray into the screw holes as well.
< < READ CLOSELY > >
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. Put the rest of the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. Let the bike warm up then set the idle speed. This process should get you back on the road.

SOURCE: how do I clean the carburetor?

ALWAYS have a fire extinguisher on hand when working on carburetors.
Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).

Drain the carburetor. There should be a screw on the lower side or bottom of the carb float bowl. Remove the screw then replace it after the fuel drains. Install a new stock NGK spark plug and clean the air filter. If the bike still doesn't start and run properly then shut off the gas and remove the carburetor from the engine.

Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Remove the idle screw and the air screw on the outside throat of the
carb and spray into the screw holes as well.

SOURCE: My 50cc 2 stroke engine won't start, it has fuel

Hi and welcome to FixYa,

A couple of ideas:

  • fuel to the carbs - as you posted checks good;
  • fuel inside the carbs - loosen the drain screw at the bottom/bowl. Check for quality / quantity of fuel;
  • fuel into the combustion chamber - check the plug (would be wet).
For a no start 2 stroke engine with your described condition, a possibility to consider is too much / unburned 2T oil in the lower combustion chamber; remove sparkplug, air dry (or use compressed air).

Good luck and thank you for asking FixYa.

Hi, David engine design is very easy to identify:
TWO STROKE
1. Two strokes red line around 12,000-16,000 RPM.
2. A reed valve is in between the carburetor and cylinder head.
3. The exhaust has an expansion chamber.
4. The muffler has a small diameter tail pipe.
5. The exhaust has a high pitched Bap Bap sound.
6. Small scooters and small dirt bikes are generally 2 Stroke.
7. Older models had adjustable throttle actuated oil injection.
8. Older models had a premix ratio of 2 stroke oil and gas.
FOUR STROKE
1. Four strokes red line around 6,000-8,000 RPM.
2. Four strokes have camshafts and valves.
3. Mufflers have large diameter outlets.
4. The exhaust has low pitch deep rumble sound.
5. 350cc and larger engines are usually 4 strokes.
6. Four strokes have separate oil tanks that feed an oil pump.

I took scooter for a ride everything worked fine get back to garage and fuel is leaking out of carborator to which it drained the fuel tank. Do I need a new carb or what's the problem.


Jason, You can replace carburetor or have the old carburetor rebuilt to fix your gas leaking problem, either float is stuck or if carburetor equipped with a solenoid shut off, are the actual problem likely.
Check the attached links,instruction and guides, Good luck
