Adjusting carburetor air fuel mix

FH601V Kawasaki.
Carburetor is not delivering the proper fuel/air mix.

Can be any if the following.

Bad fuel.
Water in fuel.
Fouled Carburetor.
Poor compression.
Poor spark.

I'd start by draining BOTH the fuel tank and the carburetor fuel bowl. Refill with fresh fuel from a station.

Identify if both cylinders are firing. The Kawasaki OHV engine requires periodic valve lash adjustment. A general tune up may be in order.

It is a standard 350 Chevy with no real modification. .... missing something or can they be in a different location on my carb ( 81vette rochester quadrojet ). ... There are two fuel mixture adjustments on the rochester Carburetor.

check the lambda sensor in the exhaust system
ecu fuel mix sync

On most engines, fuel from the fuel line enters the carburetor's fuel bowl, a reservoir where a float, similar to the float ball in a toilet tank, regulates the fuel level. From there, a metering device called a jet lets fuel into the emulsion tube inside the pedestal, where fuel and air first mix. (Older models include an adjustable jet; newer models contain a fixed jet.) Fuel travels through the emulsion tube to the main passageway in the carburetor, called the throat or venturi, where further mixing occurs.

Do you have a Holly on that ? if not then, you have to pull the carb. apart to adjust the fuel/air mix, are you talking about the idle air mix screws, this only adjust the idle mix, not the fuel ratio when running above idle, I have seen slots (screw driver) oval, hex screws, your going to have to see which one you have, take the air cleaner off and reach it from the front of the van.

you wont and you cant ,doesnt have a choke ,its computer controlled fuel injection

­T­he goal of a carburetor is to mix just the right amount of gasoline with air so that the engine runs properly. If there is not enough fuel mixed with the air, the engine "runs lean" and either will not run or potentially damages the engine. If there is too much fuel mixed with the air, the engine "runs rich" and either will not run (it floods), runs very smoky, runs poorly (bogs down, stalls easily), or at the very least wastes fuel. The carb is in charge of getting the mixture just right.

Your car should have fuel injection not a carburetor. The air/fuel ratio is controlled by the onboard computer. If it is running rich, I would suspect an O2 sensor, perhaps a dirty air filter, needs new spark plugs, or even a new catalytic converter. You need to have the computer scanned for trouble codes. The codes will give us a place to start looking for the cause of the rich mixture.

First your car is not equipped with a carburetor. That said the Carburetor is what supplies fuel to the engine based on the load, there are no cars sold in the USA that use a Carburetor today..

Theese are NON SERVICE Items If there Is a Problem From them The PART NEEDS REPLACED You will Only Make it Worse
