SOURCE: How do I adjust the carburetor on a Poulan 38cc

Turn both jet screws CW to stops (lightly), then back out CCW 1-1/2 turns each. This is a basic setting and the engine should start and run. Be sure to check the fuel filter, air cleaner, and muffler for plugging. Start the engine and allow to warm up--pull the throttle full on and adjust H jet needle CW until the engine starts to speed up, but still 4-stroking. Proper adjustment is reached when the engine 4-strokes at speed, but immediately 2-strokes when cutting. Release the throttle and adjust L jet needle CW until the engine idles fairly well, but will allow the engine to 'follow the throttle'. Set the idle speed screw so that the chain stops turning, but the engine will continue to run. Hope this helps!

SOURCE: what are the high and low carburetor settings on a

are they two separate screws? one for fast, one for slow.for the slow setting, first start the saw then screw until motor runs smooth without chain moving....if to slow the motor will stop....for fast screw....rev motor flat out then adjust so it screams its head off so to speak....it will need all its power for cutting wood so don't think you are opening it up to much as its designed for it.

I have 1999 Polaris Sportsman 500. Just replaced the carb, but now it will not start or run. I've adjusted the idle screw, etc. Ideas?


Adjust idle and mixture screws to default positions - start it and then make the necessary adjustments. Idle speed, low and high speed mixture settings if applicable..

Ryobi 725r trimmer carburetor adjustment


Turn both low and high adjustment screws carefully clockwise all the way in - do not overtighten.. Then back out each two full turns. Set the idle speed control for highest setting. Prime and start and let it run and warm up for about 15 seconds - then lower the rpms a tad and then adjust the low end screw for highest rpm. Then reset the idle to lower reasonable level. You may have to go back and forth with those two adjustments till it runs fine at low idle speed..

Then accelerate to highest speed and set the high adjustment for highest rpm. Then go from idle to high speed. If not smooth a small adjustment on the high speed screw is in order. Keep doing that until you get a nice smooth transition form low speed to high speed.

Settings for mixture screws


Most Chain Saw Engines Have Three Carburetor Adjusting Screws:
1. Idle Speed/Throttle Stop - This is the adjustment that controls how much the throttle valve (butterfly) stays open when the throttle trigger is released. If this adjustment is set too low, the engine will die when the throttle trigger is released. The throttle valve (butterfly) simply cuts off the supply of combustible air/fuel and the engine stops. If this adjustment is set too high, the high idle speed will cause the centrifugal clutch to engage and the chain will run. This is a dangerous condition and should never be allowed.
2. Low Speed Fuel Adjustment (marked L on carb, this is the low speed jet)- This is the adjustment that controls the proportion of fuel in the combustible air/fuel mixture at idle speed. An adjustment that is set too rich will cause the engine to load up and die at idle speed. A mixture that is too lean will starve the engine and cause it to race or surge. An extremely lean adjustment will cause the engine to die, too.
3. High Speed Fuel Adjustment (marked H on carb, this is the high speed jet) - This is the adjustment that controls the proportion of fuel in the combustible air/fuel mixture at cutting speed. It would not be accurate to say that this is the most important setting, because all of these adjustments need to be accurate for a saw to perform its best, but this is the adjustment that determines how the saw runs in the cut. An adjustment that is set too rich will not allow the saw to reach the RPM level necessary to build maximum power. Throttle response may also be sluggish and the engine would smoke and perform poorly. A mixture that is too lean will allow the engine to reach an RPM level where bearing failure and cylinder seizure are likely. It will also lack power in the cut and tend to run very hot.
The preceding information briefly explains rich and lean running conditions. It also identifies the three adjustment screws and their function. It should be noted that some chain saws lack the high speed adjustment needle. These saws have what is called a "fixed jet" which is set from the factory. "Fixed jet" carburetors are used to prohibit the saw operator from setting the adjustment too lean and damaging the saw. Unfortunately, they also often prohibit the saw from achieving maximum performance.

Stihl FS 80 carburetor settings for high and low screws


Hi F Del
Before you remove or try to adjust your low and high speed jets you should always count the number of turns it takes to lightly seat the idle mixture screw and high speed needle adjusting screws.
Be sure to write the number of turns down on a piece of paper so you will know how many turns from the seated position to open the jets when you go to reinstall them, or if you remove them for cleaning or replacement.
If you have aready tried to adjust them then the adjustments below should get it running for you for final adjustment when warm.
Normally you will adjust your idle jet to 1/2-3/4 turn open from the bottom seated position.
Then you will re-adjust the low speed of the engine when the engine is warm by turning the idle screw in or out till the engine runs smoothly at idle speed, around 1200 RPM.
The high speed jet is adjusted to 1 1/2- 1 3/4 open from the bottom seated position, after the engine is warm.
Then re-adjusted by turning the High Speed jet adjustment screw in or out till the motor runs smoothly at high speed.
Alway use the "lightly seated" method if you have not changed the screw settings.
Please take time to rate me

Have an old pioneer p38 chainsaw, belongs to the old man. hasn't been started for a few years. replaced fuel gave it a clean thats all, wont go.


You need to disassemble the carburetor and check the diaphragm. You need to blow nozzle of carburetor. If the fuel was left in him, now it has remaining traces of oil. You can try to start with a small pump to inject fuel directly into the intake of the air into the carburetor. Of course, the spark has to be here to start. Older chainsaws had a switch and a capacitor, which is very difficult to adjust. Newer chainsaws have electronic ignition, so it is easier for test. Most of carburator has three buttons to adjust. L (low), H (high) for fuel injection at low and high speeds. There is also a minimum (the chain must be stationary if it is well tuned). The chainsaw is set at low rpm throttle with screws ( L ), and its vivacity is set at high speeds ( H screw ). In the beginning is good put both to set at 1.5 turns from full closure. And then, if the chainsaw starts, you can adjust a carburetor work. Careful with adjusting with H due to high speed. Good luck!

The owners manual for my Ryobi 210 describes carburetor adjustment but the photos do not show which screw is the idle mixture adjuster.


The Low speed adjustment screw is the one marked as "L" and would be adjusted during:
1. Idle - to insure running smoothly, and
2. Acceleration - to transition from Idle to High Speed.

The High speed adjustment screw is the one marked as "H" and would be adjusted during:
1. High speed or Wide Open Throttle. Turn about 1/8 either way to gain top RPM's and then back off slightly.

The final screw is an Idle Set screw. This screw sets the actual speed of the Idle and is the screw attached to the end of the throttle cable as it terminates at the carburetor. Turning it:
1. Clockwise - increases RPM's (speeds up motor)
2. Counter Clockwise - reduces RPM's (slows down the motor)

Carburator tune up of charadade 1992 sedan. The engine is running too fast while idle at 1200 r.p.m.


Before you start check the status of your choke. One that is stuck on will cause a high idle. If the choke checks out, proceed to the following:


You should have what's called a 2 needle carburetor. A larger screw adjustment for idle, and a smaller for high speed.

Start by adjusting your low speed (idle) needle until you reach the desired idle. I prefer about 850rpms. Do this with the engine running and adequately warmed so that your adjustments are not thrown off by the automatic choke.

Next slowly open up the high speed needle. As you open it your idle speed will gradually increase. Adust it in 1/8 turn increments, pausing after each adjustment to allow the changes to take affect. Keep opening it until you stop increasing your rpms, then take it back 1/8 of a turn.

Next readjust your idle mixture screw so that your idle is back down to 850rpms.
