On that model the low adjustment may be factory set, and the adjustment screw is replaced with a roll pin. The high adjustment has a cover on it that can be prised free revealing the screw beneath. Turn screw all the way in (clockwise) GENTLY dont overtighten only to when you feel slight resistance on the screw. then back out 1 1/2 turns. This is the base setting. Turn at 1/8th turn either way until good high speed rev is obtained, but no further in than 1 1/4 turns out, or you will run the saw lean and cause damage. Check and replace your plug if fouled at all.

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.

I have a husqvarna 125b gas blower and it came missing its manual. Can you explain the high and low speed idle controls : which is which and what is used to adjust them Thanks


A special tool is required to adjust the carb screws, it should be set up from the factory for the best emmissions, so there should be no need for you to adjust them, however the L screw controls the low speed and acceleration up to half throttle, the H screw controls the max rpm, the the third screw just controls the idle speed, if you need the tool it is part no. 530035560, both screws are fuel, not air screws, screw the L screw in until you get the highest revs, then back it out 1/4 turn, screw the H screw in for the highest rpm, now back off 1/4 turn. if the machine does not pick up smooth increse the L screw bit at a time until it does, if the full revs sound too rich, screw the H screw in a very tiny bit.

Runs full throttle but dies when let off gas, carb new, plug new, fuel line new, ?


It could be as simple as carb adjustment,if it was a new carb it will be set at base settings, which is just intended for running the machine ready for fine tuning for individual machines, unfortunatly you need a special tool to make an adjustment, part no. 530035560, once you have this tool you need to unscrew the L screw on the carb to richen up the idle mixture.

Hello, I need to adjust the low/high idle on my Husqvarna 435 X-Torg. I can't seem to find the necessary tool (looks like a socket "screwdriver"). Can you help? Thanks, --Scott


There is a special tool required, pt no. 530035560 you should also have a rev counter, do not exceed the max engine speed of 12500 or you could seize the engine.

Where can I get the special tool to adjust the jets on the carb.


The special toll your looking for is a thin bladed screwdriver. Some carbs have and idle and a "H" (high) adjustment only Others have third setting for "L" (low). The adjustment for idle (top of carb) is a personal judgment call but it should remain running at a low RPM. The adjustment for "H" Is done with full throttle and to the pint that it just does run at full speed without missing. DO NOT set it too lean (clock wise) or you will end up with a short lived blower. As far as setting the "L" speed (on models so equipped) you dial that one in by allowing the unit to idle then rapidly accelerate the engine to full speed. If it hesitates you turn it no more than 1/8 th turn each time and keep repeating the accelerate to full throttle rapidly routine until the hesitation stops. A few of these models have a plastic cover over the "H" adjustment screw. On some of them you can do about 1/4 turn with the cover installed but have to pry it off the jet screw head if further adjustment if required.

Thanks for choosing FixYa.

How to adjust the low and high settings on the carb


With all the new EPA guidlines on emissions there are many new type of carbs.The older type was easy, If its a walbro or zama brand and it has 2 adjustment screws as well as an Idle speed, preset the low and high at 1.25 turns out from set, start the saw, run it to full throttle,adjust the high speed needle counter clockwise untill you hear the engine start to flutter. You want to year the flutter about once every 4 seconds.then let it idle,adjust the low speen till it runs smooth then make it 1/8 turn richer. Many of the new carbs require special tools to adjust, not brain surgery, just to keep the air cleaner..

Idle seems too low. runs great, when no throttle, stalls. maybe idle too low. no manual, need to know where idle adjustment screw is


If you haven't already adjusted the carb there are usually 3 adjustments. H - adusts performance at full throttle (how it cuts in the wood). L - adjusts performance at idle and accelleration to full throttle.It sounds as though those are fine. The third adjustment T - is the throttle or idle speed (often away from the other 2). If my saw that is the one adjustment I'd make. You supplied no make or model, it is difficult to provide what you requested without them. HTH
