These tools are not available to the public. There is a specific penalty that can be levied if the owner adjusts these screws. A local dealer should make the adjustment.
The tool is not available through Husqvarna.

SOURCE: can't find a husqvanna chain saw carburator

You may have the one that uses splined adjustment screws rather then limiters.If you do you can order this from your husky dealer.You can tell if you have limiter caps by shining a light through the screw hole and see if caps are white or red.If black you have round splined needle ends that take a hard to get adjustment tool.

SOURCE: What tool do I need to adjust the high & low

Should just be a little bladed screw driver, most are, turn the screw very little, 1/4 turn at a time till something changes, they are sensitive. If you run out of adj and nothing has changed, turn the screws in all the way, both of them, then out 1 1/2 turns, this will get you running, you can fine tune from there.

SOURCE: how to adjust the carburator

Unfortunatly there are special tools required to adjust the screws, the screws are set from the factory for the best emmisions. The screws are anti tamper with splines rather than a screw driver slot, before making any adjustments check fuel filters and hoses first, it is not good to try and compensate for fuel blockages by richening the carb, max rpm must be set up useing a engine tahco and should not exceed 12500

Hard starting


Starting any chain saw can be a bit finicky. How many hours has the saw done since new ruffle? Over about 10 and the saw would have run in and will need to have the fuel adjusted. What fuel to oil ratio are you running?

Just as a point, you might know this but I only pull the saw over 3-4 times with the choke in. Then try to start with it off.

Hard to start, when i get it started it fine shut it off try to start it hard to start


Hi
General advice aplicable for all gas powered chain saws;
Clean air filter regularly.
-Adjust spark plug gap (very important). A faulty gap will either cause poor spark or a overloaded and damaged spark plug coil.
-Use correct good quality spark plug
-Use correct oil/fuel mix ratio and correct oil.
-Do not use old premixed fuel if you can avoid it.

Carburator adjustment;
-idle speed setting screw should be set so that the saw idles well, without engaging the chain. If you normally have to press the gas lever to be able to start it coul indicate a to low seting. Clockwise will increase idle speed. This screw is found near the carburator and is slightly larger the the two adjusment screws.
- fuel-air mixture screws can be set to standard factory setting as a start. Normally there are 2 screws labeled L and H, for Hi and Low rpm band adjustments. Factory setting are usually 3/4 turn out(anti clockwise) from fully closed setting for both (clockwise to closed position).
Experiment with adjustments by 1/8 increments at the time. Anti clockwise turning will increase fuel to air ratio and opposite. Warm weather will require a slightly leaner mix and cold weather will reqire a slightly richer mix(more fuel). Low rpm setting only serves the idling performance. The Hi rpm setting can be evaluated by removing the spark imediately after running at full load for a period. The spark plug should be dry, and be lightly brownish at the electrodes. White-ish color indicates low fuel to air mix, and this causes too high combustion temperature. A black colour indicates a too high fuel to air mix ratio, and it causes carbon build up on the plug.

If you still have starting problems, cylinder/piston compression is the next to check for. This is a more extensive job and should best be left to professionals, unless you are very skilled and have access to special tools required. Compression on modern saws are very delicately balance, so the slightest damage to either the rings, piston or cylinder can cause problems. Is is not alwas worth to replace the cylinder and piston kit, so compare prices and ask for advice at your dealer.

I hope this helps you.

I have a problem keeping my saw to idol, other than that it runs fine. what are my options?


Adjust the Low idle screw so that it doesn't die out. On most saws, to adjust the idle, look for an opening that has an L next to it (there is also one for high idle speed with an H next to it). Use a small screwdriver, and be careful--many of the idle adjustment screws are plastic so you don't want to strip it.

What is the oil mixture for husqvarna chain model 235


50:1 fuel to oil ratio is correct for this saw. Be sure to use modern synthetic saw oil, not a petroleum product like outboard motor oil. Premix the fuel and oil in it's own can, and shake thoroughly just before filling the saw each time. With these modern fuel/oil ratios, serious engine damage can occur if not thoroughly mixed each time. Hope this helps!
