How to adjust the carbs on a Ninja 250?
1. Get a bucket of chemdip from walmart. Soak the carbs and metal parts for 24 hours. Remember to fully disassemble including jets, needle seat, and idle mix screws. Do not put anything but metal in the chemdip. I put the small parts into a float bowl so they don’t fall through the basket.
Where to set the air fuel mixture screw?
Set the screw in the middle between the rough- and irregular-sounding spots. Turn the screw back clockwise until it is approximately in the middle location between where the engine’s idle sounds irregular and rough. This will set the engine at a regular idle speed.
How to get more fuel through the CARB of a pilot air screw engine?
The only way to get more fuel through the carb of an pilot air screw engine is to enlarge the pilot fuel jet which is what limits/sets the flow of liquid; all you are doing is adding/removing air from the pilot circuit mixture when you turn the adjusting screw. renogeorge Let’s ride!! All wrong, above…
What’s the name of the air fuel mixture screw?
Note that this process is the same for any type of engine with an air fuel mixture screw. It could be a car, motorcycle, scooter, ATV, or anything else with a carburetor. Tip: An air fuel mixture screw is also known as an idle mixture screw.

What kind of jet does a Kawasaki carburetor use?
On the CVK40 it consists of a collar and what Kawasaki calls a holder. Most 4-strokes have pin holes along the length of this brass jet. These pin holes allow air from the air jet to premix with fuel from the fuel jet to start the mixture emulsification process before it enters the venturi. Primary type carbs use a solid jet, (no pin holes).
How many parts of fuel does a carburetor need?
The ‘mixture’, (a mixture of fuel and air, your engine’s ‘food’), is theoretically ideal at around 15 parts of air to one part of gasoline by weight, (not volume). The outer limits are 12:1 and 18:1 . Too rich and you’re wasting fuel, spewing more pollutants, diluting your oil, fouling engine parts, and performance suffers.
