Rebuilding a 250 cc roketa scooter and mounting radiator s\\and gas tank

SOURCE: I have a Roketa 150cc Sicily Scooter (2006). It

Here's the deal. I have never even heard of your bike brand but I have 18 years in bike repair. If you promise not to give me anything less than a "helpful" rating I will tell you how to do the fix based on the assumption that the bike has a standard carb and not a CV carb. The standard carb has a top "cap" that unscrews from the center of the carb body.
.
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. Turn the gas back on and wait a minute for the carb to fill with gas. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine. Now unscrew the top cap and pull the slide out of the throat of the carb. When you re-install the slide, be sure the long notch on the side of the slide lines up with the small pin inside the throat of the carb.

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.

Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two adjusters down. Only screw these in until they LIGHTLY seat. Now turn each adjuster one and one half turns outward. Before putting the slide back in the throat of the carb, move the clip on the jet needle one notch lower. 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. This process should get you back on the road.

Please rate this solution. Thanks!

Hi and welcome to FixYa,

On most versions of Roketa 150cc engines, the choke is automatic and electrically driven..  It is integrated with the carburetor.

Good luck and thank you for asking FixYa.

SOURCE: what can make a 50 cc roketa scooter not get any

If it just die on you changes are;
Faulty spark plug.
Blown fuse.
CDI box is shot, Knock offs are about 25 to 30 bucks
Hope this helps you out.

Tweek the tick over screw (idle screw) on the carb.
Any more information just ask me. :)

Hope this helps.

You might get lucky with new spark plug(s) and I assume you mean 2-stroke oil. Otherwise, drain tank and replace any fuel filter in system, then re-try with fresh gas and new plug (s)
