Hi Tony
Here are a couple of hints and a link to a youtube video to help you out
*************************************************************************
Sounds like you have dirt/debris in your caburetor jets,fuel passages or a diaphgram that is becoming non-flexible.
Check/Clean/Replace your Air Filter, a dirty air filter can make your engine run to rich with fuel.
Note: You should also check for carbon build-up in the exaust,as it can have an effect on starting and running of the engine if the carbon build-up is heavy.
Also be sure to check and clean your spark arrestor in the exaust,if you have one installed on your engine.
Note: ALWAYS USE COMPRESSED AIR TO CLEAN YOUR JETS AND PASSAGES, VERY IMPORTANT.
Note:Before you disassemble the carburetor:
Write down on a piece of paper or take a picture of how the linkage attaches to your carburetor for later reference when you go to reinstall your carburetor.
Mark each piece with a awl, or some kind of instrument that will make an alignment scratch before you disassemble the carburetor into separate pieces.
That way you will know which way it goes back together when you reassemble it.
Sometimes you can get by with priming the carburetor or by using a very small shot of starting fluid and letting it run a few times like that, and it will flush the gunk out of the jets,but most of the time you will need to rebuild the carburetor.
Be sure to check your fuel tank for water and dirt/debris, if there is water/debris then you need to clean your tank.
Check you fuel line condition after a while they will degrade and need replacment.
Check/Clean/Replace your fuel filter if you have one, normally they are located in the fuel tank of chainsaws and weedeaters.
When you remove your fuel lines from the carburetor be sure to make a drawing to how the lines are connected to the carburetor or take a pictue for later reference.
Normally the big line will be the line the fuel filter is connected to inside of the tank.The smaller of the two lines is the return to the fuel tank from the carburetor after it is pumped thru the carburetor by the primer bulb.
Make sure you are using fresh fuel...and oil if your using a two cycle chainsaw or weedeater with the oil to the right mixture...too much oil as it can cause hard starting and excessive smoking.
If the chainsaw/trimmer is over a couple of years old, then I recommend that you buy and install a new carburetor repair kit,because the diaphragm will get hard and that will cause it to be hard to crank.
The diaphgram may look good and flexible, but it can be deceiving and not act as a fuel pump as it should because it has become too hard and will cause hard starting,start and run and shut off, etc.
When you clean your carburetor, I recommend that you use a laquer thinner type cleaner to clean and dissolve the laquer build-up in the float and needle jet passages.
Be sure to remove all plastic and rubber parts before using the laquer thinner because it can dissolve the plastic parts and render them unuseable.
Be sure to use COMPRESSED AIR to blow out all the fuel and air passages.The higher air pressure is needed to blow some of the trash/debris from the fuel or air passages.
Be careful when blowing out the passages, because there are sometimes small rubber type seats in the bottom of some of the passages.
Keep in mind that the float (if you have one) for the carburetor must be level when you go to reassemble the carburetor or follow the instructions you get with the carburetor kit, or you could also ask the parts man that you get your kit from.
When you clean your carburetor and remove the jet screws, you will first need to lightly seat the jet screws.
But before you lightly seat the jet screws count the number of turns it takes to seat the jet screws from their original position.
Be sure to mark the turns down on a piece of paper.
That way when you put the jets back in, you know to lightly seat them first and then turn them back out to their original position before you started.
Note:
The little spring inside of the carburetor goes under the float arm.
That is where your fuel inlet needle/float valve is located...on the arm at the end.
Normally there is a small indention in the carburetor base and a small protrusion on the underneath of the float arm where the spring will be in the right postion for installation.
The spring will set in the indention and you will install the float arm with the needle/float valve and float rod into position over top of the spring,you will push down until it is in position and then you can tighten the screw that holds the float arm assembly in position.
Once you have your carburetor cleaned/rebuilt that should solve your problem.

The carburettor how to adjust the air and fuel mixture on the carburettor


Find the adjustment screws on the front of the carburetor. Then Start the engine and let it warm to normal operating.
Adjust both screws equally and find the right mixture.Bring both screws up slowly and listen until the engine purrs smoothly. Any raggedness or rattling is a sign of too lean a mixture. Keep turning until you find the sweet spot.

What is the initial carburettor adjustment for a mac 120 MCCulloch chainsaw?


Hi williamsc32...
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.

How do I adjust(set)the engine speed govenor on an Atco 114cc engine.


Some ATCO carburettors have more than one hole for attaching the throttle cable to the governor pivot, which will allow some variation of the speed setting by moving to a different hole.
Just before the throttle cable reaches the governor pivot it passes through a metal lug (separated from the pivot by a spring) here there is threaded screw on the throttle cable - loosen or tighten this to adjust running speed.
There is also a throttle stop adjusting screw which on the side of the carburettor which you can adjust to set the idle speed.

I have a 450, and I would like to increase my bar oil output. Where is the adjustment screw? Please!


There is no adjuster for the Husqvarna 450. Husqvarna recommend that if there's not enough oil reaching the bar that you slow down the engine by adjusting the carburettor screw. I have the same saw and also wanted to adjust the oil flow. I didn't change the carburettor and it's still cutting away without doing any damage. It's meant to use less than a tank full of oil to the tank full of fuel when you're cutting near constantly. With stops in between it will use more fuel and less oil.

Starts, idles and runs but quits after a few seconds of cutting


Check the air cleaner and muffler for plugging. One screw adjusts the idle stop (idle speed) position and the H and L jet screws set fuel mixture for high speed and idle speed mixture respectively. Turn both jet screws CW to stops (lightly) then back each out CCW 1-1/2 turns. This is a basic setting and should allow the engine to start and run. Start the engine and allow to warm up. Pull the throttle full on and adjust H CW until the engine starts to speed up, but 4-strokes. Correct adjustment is when the engine 4--strokes running free, but immediately 2-strokes when cutting. Release the throttle and adjust L needle CW until the engine idles fairly well, but allows the engine to 'follow the throttle'. Adjust the idle speed screw so that the chain stops turning, but the engine will continue to run. Hope this helps!

How and where do you adjust the synch on 1986 gsxr


I can help with this.
On the earliest models they had slide type carburettors. This is to say that the slides were actuated by the throttle cable acting on a linkage that physically lifts the slides in the carburettors. This type of carburettor has its balance(syncronization) adjusters under the caps on top of the carburettors.(the cap isn't round & has 3 screws in it)
Number three carburettor is fixed & dosn't get adjusted.

You'll have to put the bike next to a bench & attatch a long piece of fuel hose from the tank to the fuel hose on the carburettors.You can join the two pipes together using a short piece of hose that snuggly fits on the outside or inside of the two hoses. You can also join them with a suitable shirt piece of metal pipe,or what is called here in Australia a P3 barb.These are available from tool suppliers that supply air compressor hoses & fittings.
(I made a remote tank from an old lawnmower petrol tank,a long piece of hose & mounted it on a tall stand.Under it I have a tray with all my different adaptors in it.)

You adjust number 2 cylinder to the same vacume reading as number 3 cylinder first.
Now adjust number 1 cylinder to the same vacume reading as number 2 cylinder.
Next adjust number 4 cylinder to the same vacume reading as number 3 cylinder.
Recheck that they are all the same & your done.
The adjusters are of the screw & locknut(8mm)type.
You can struggle with an 8 mm ring spanner & a flat bladed screwdriver,buy an adjusting tool(genuine, or non-genuine from a bike shop) or make one.

To make one you weld a bar onto the side(at the top)of an 8mm extended quarter inch drive socket.Then find a long small screwdriver that will fit down the hole.

After you make each adjustment,stop the engine & open the throttle wide open & release a couple of times.(This seats the slide).After diong this re-start the engine & re-check your adjustment.
I place a fan blowing on the engine to help control the engine temperature as the adjustment can be a bit of a fiddle.

I prefer to use mercuary type vacume guages as they dont go out of calibration.

If you are using dial type guages check that they are all reading the same by checking them all one by one on the same cylinder.
Some Suzukis' have a pipe (covered with a black rubber stopper) at the top of each carburettor(at the front) & others have an allen screw on the cylinder in front of the carburettor manifold rubber.
If yours has the allen screw you will also need adaptors that screw into the hole once the allen screw is removed.

If you bike has diaphram type carburettors on it(you'll be able to recognise this by the top caps of the carburettors being black & roundish in shape & held in place by 4 screws), the adjusting screws are between each carburettor & are the spring loaded type.
The adjusters are located in-between each pair of carburettors visable from the top.
These are easier to adjust as there is no lock nut to struggle with & all you need to turn the adjusting screws is a long (flat or phillips)screwdriver.
Again, balance the center two first,then the left pair then the right pair.

This procedure is applicable to all in line 4 cylinder motorcycles (even most fuel injected ones.

It sounds as thought he convergance needs to be adjusted. You will need to push the auto adjust button or go into the menu and do a manuel adjust. Any adjusting instructions should be listed in your Operator Manuel. If you require more assistance in this matter, please write back. Good Luck
