Even if a carburetor is brand new, it still needs tuning. Your engine, its condition, your location, and the weather all come into play and the carburetor needs to be adjusted properly. Adjusting a carburetor is something you perform frequently.
All aftermarket exhaust manufacturers recommend re-jetting or adding a Fuel Processor to enrichen the air/fuel mixure when changing to any aftermarket exhaust.
Typically, there`s a 12:1 or 15:1 ratio of air to fuel, and when there`s too much air or not enough fuel, it causes sneezing or popping sounds in the intake.
The engine should rev smoothly and quickly as soon as you apply throttle. If the vehicle is displaying any sort of sluggish performance or misfires when you apply the throttle, then more adjustments are required.
You should prime the carb, and then check the float level prior to starting the engine. Other carburetors must be opened to access and set float levels, so this procedure is best performed before the carb is installed. With the carb installed and the floats set, it`s time to set the air/fuel idle mixture screws.
This means that the new parts are clear from any sensors or meters that the ECU (Engine Control Unit) may need to run the vehicle. They may let more sound flow through, but CB systems do not affect the aspiration of the engine. As a result, Cat-Back exhaust systems do not require an updated tune.
This method involves looking at the base of the spark plug insulator (white part of the plug) for a slight coloring on the insulator just above where the insulator comes through the steel case. If the mixture is too lean, it will leave no color, while a rich mixture will cause the fuel ring to become more prominent.
To check fuel delivery, remove the fuel line where it enters the carburetor and use a length of rubber hose to direct the flow into bottle or similar container. Fuel should pulse out in strong spurts if your engine is equipped with a mechanical fuel pump (electric fuel pumps are more of a steady stream).
Engine Running Rich Symptoms

If your car is running rich, you`ll likely experience these symptoms: Low gas mileage. A strong smell of gasoline, especially when idling. Check engine light warning.

If your carburettor has a main jet adjustment screw at the base of the float bowl, turn the screw clockwise until you feel it just touch the seat inside the emulsion tube. Then, turn the screw counterclockwise 1 to 1-1/2 turns. Replace the air cleaner assembly and start the engine for final carburettor adjustments.
A failing carburetor directly affects your vehicle`s fuel efficiency, so you`ll find yourself spending your hard-earned cash at the gas pump more often. The improper fuel/air mixture can also cause avoidable engine damage. Call AutoFix if you suspect you have carburetor trouble.
The ideal chemical air-fuel ratio, in which all the fuel is oxidized, is 14.7:1, that is, 14.7 parts air to 1 part fuel. A “rich” condition means more fuel is being used, an air-fuel ratio less than 14.7, while a “lean” condition means less fuel is being used, an air-fuel ratio higher than 14.7.

Any carbureted engine should be mounted with the carburetor base level. But level with what? Level with the ground at ride height, which means you have to set the vehicle up at its intended ride height and level it side to side before even starting to mount the engine.

I have a husqvarna 323L string trimmer. I stored it after running the tank & carb dry for about two years. I fueled it, then started it, & it ran for a minute then died like I turned the switch off. Since it would not restart, I found the fuel filter had broken off the hardened fuel line & it sucked gummy crap out of the tank & into the carb. Failing at cleaning the carb, I finally put a new carb on it & replaced the pump, hoses & filter. It has ran good till this year. I winterized it with stabilizer & left it with a full tank over the winter. The gas in the tank was gone when I got ready to use it this year. I filled the tank with premix, checked for leaks, then started it. It would run fine for about half a tank, start idling poorly (lean) then cutoff & refuse to restart till I refilled the tank. I finally found the tank had cracks & was letting pressure out of the tank & apparently this was causing the carb to lose it’s ability to siphon gas out of the tank. So I replaced the tank which came with new hoses & a filter, which I properly installed to the carb. It cranked right up, but when it runs a half tank, the carb quits sucking gas out of the tank. When I pump to prime the carb, it moves the fuel into the carb, but the pump never gets hard like it does when I prime the carb when the motor is cold. I have to keep refilling the tank, prime, & then it starts & runs until the tank gets about half empty. The new fuel filter is down in the gas tank properly, but It will not run after it shuts off until I refill the tank & prime. I’m baffled. New tank, new hoses, new filter, new carb, & I can find no leaks in the fuel system. It runs strong. The 323L is a two-stroke & it always cranks on the second pull from cold on a full tank. Any ideas?

Need to know what carb screw adjustment need to be set at weedeater starts for about 4-7 sec then shuts down put new hoses on checked gas filter and cap checked out ok. i pump the ball about 10 times ,pull cord &starts for about 4-7 sec then shuts down,like no gas or electrical problem. i played with the screw settings & dont know where they shoould be set at . had carb all apart ,put in new plug doesnt seem to matter what i do it does the same thing . any thoughts?also when it starts the motor will rev up when u hit the gas and when it shuts down the gas hose from the tank is still full of gas
ANSWER : If there is a choke adjustment you should set that at full until the trimmer warms up, don’t touch the gas. Then repull start at half choke, don’t touch the gas either at this time. Then start at no choke, and then set your idle on the carberator with the adjustment screw. Also don’t push the primer bulb so many time you will cause the spark plug to get flooded and drown out the spark, which is exactly what is happening.

My 26bv blower vac starts and runs fine but shuts off after between 1 and 3 minutes. It will usually start again immediatly but then shuts off again. Any idead what the problem is?

I have adjusted the carburetor because previously it would only run on half choke. Now it runs fine but won’t stay running as described above. What are the factory settings for the carb?

ANSWER : I have exactly the same problem. Has anyone an answer as to how to fix the problem? I can keep turning the knob from choke to medium choke to keep engine from stalling but it is a constant battle to keep engine going.

Does not run, will start with starting fluid – Mantis 2-Cycle Tiller
ANSWER : You should never use starting fluid on this model.

Add a couple of ounces of 100% acetone (available at Walmart) to some fresh fuel. Attempt to start for several pulls. Let sit for several minutes and repeat until it sounds like it wants to run.

Then watch this video and do it:
