Dan, Most idle screws want to be 1 to 1.5 and most mid or secondary screws start at the same setting. This may or may not be enough for your machine, but usually will get the unit enough fuel to run, then set them properly , and finilize when unit is fully warmed up.

What is carburetor setting on a2.3 chainsaw

There is no fixed carburetor setting on these engines, just two screws to adjust low-end and high-end operation. Special tool may be required, there are about a half-dozen screw head standards. Check eBay for tool. Get the engine to run and idle fast (idle adjust) so it doesn't stall, adjust low-end screw so that engine doesn't hesitate or sputter when accelerated. Adjust high-end screw to run fast and smooth on full throtle. Readjust idle to normal.

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.
Please take time to rate me

Mcculloch power mac 310 chainsaw Carb adjustments

The idle adjustment screw will probably have a spring on that screw and will push directly on the throttle linkage. You just adjust this screw until the engine idles like you want it to. I believe on saws, they have to idle to where the clutch will not engauge when the engine is at idle. As for the mixture screws the low speed screw (L) you adjust when the engine is at idle, the high speed screw (H) you adjust while the engine is running with a good bit of throttle. Once you get the idle speed where you like it, then all you have to worry about is the mixture screws. When adjusting the screws, just listen to the engine, to much one way and the engine will run rough and sputter, to much the other way the engine will run rough and maybe start hunting (reving up and down). One thing to check on these small 2-strokes is that the air filter and the muffler are not clogged cause if they are, then you would be having to adjust the carburetor to make up for the air restrictions that these two problems can cause which would mean that the carburetor isn't actually adjusted perfectly.

How do u set the darb screws on a mac cat 839 chainsaw

Turn both jet screws CW to stops (lightly), then back out CCW 1-1/2 turns each. Start the engine and allow to warm up. Open the throttle and adjust the H jet needle CW until the engine starts to speed up. Correct adjustment is when the engine 4-strokes at speed unloaded, but 2-strokes immediately when cutting. Release the throttle and adjust the L jet screw CW for better idle, yet allows the engine to 'follow the throttle'. Adjust the idle speed screw so that the engine continues to run, but the chain doesn't try to turn. Hope this helps!

How to adjust idle on McCulloch Mac 2214av chainsaw

Look for 3 adjustment screws on the carb. should be three total. 1 screw is for idle adjustment. the other 2 should be close to each other, one is low speed fuel/air mix and the other is high fuel/air mix. Adjust the low fuel/air mix screw until it will idle un-added with the throttle then adjust the idle on the throttle to get a good idle speed. Next adjust the High fuel/air mix until it gets the RPM's you want it to have. It should go from idle to high speed with out hesitation or cough. . Start with 1 1/2 turn out from all the way in. Be sure the filter is clean, You can use starting fluid or old school lighter fluid to aid starting if has been sitting for some time.

The second hand McCulloch 120 chainsaw I purchased

I think the pre-adjust settings are to turn jets in all the way and back out 1.5 turns each. then:

You will find a Low and High adjustment screw. At idle turn the screw in or clockwise until the rps starts to decrease. Then start turning it out till you hit max idle rpms. Turn screw back in a quarter to half turn and it should be idling smoothly. Be careful here and get someone to hold saw if necessary but hold in throttle to full speed and do the same with high adjustment screw. turn it in till rpm starts to drop then back it out until you get to max rpm and it won't go any higher then turn it back in a half a turn.

How do you yune a muculloch mac 110 chainsaw

There should be a small screw near carburetor Labeled L and one H. Set the L or low jet first by screwing it in slowly until the engine drops RPM then start screwing it back out until it quits gaining rpms then screw it back in one half turn. Be careful on the high jet as it requires you to hold the throttle wide open. Do the same proceedure as low. Screw it in till drop them out till the RPM is maxed out then back in a half a turn. Try reving the engine several times and it shouldn't hesitate. If it does, open the H valve a small amount. Go back to idle after adjusting H valve and make sure the engine still idles smoothly or you'll need to re-adjust it again. After it's running well then adjust idle speed. Should be set a little fast but not enough that the chain turns while idling.

Craftsman 16'' chainsaw, start with very high rpm, how to adjust ?

The H is for when your cutting,it keeps the saw from stalling. The L, is for the saw when at Idle. When the L ,is adjusted right, the saw should stay running ,and the chain should not move ,that is with the break in the off position. The H screw,should be adjusted if the saw bogs down when rev ed up. A good starting point for theses screws would be a turn and one half out.
