Husqvarna Recent Questions, Troubleshooting Help & Support

Initial settings for high and low air fuel mixture screws are 1 turn out. The initial settings should allow the saw to run.

You may need to adjust the idle speed screw to increase idle speed just enough to keep it running to make the low a/f mixture adjustment. Then lower idle speed and readjust low a/f.

Once you have the low a/f set, adjust the high a/f. I usually remove the chain and clamp the saw bar into a vice. That makes it easier and safe. The low adjustment affects the high so anytime you change low you need to follow with another high adjust.


The folliwing is from the manual.

!!!
• Before any adjustments are made the air filter should be clean and the cylinder cowling fitted. Adjusting the carburettor while a dirty air filter is in use will result in a leaner mixture when the filter is finally cleaned. This can give rise to serious engine damage.
• Carefully turn the L and H-jets clockwise to the bottom. Now turn the jets one turn anti-clockwise.
!!!

You want to error on the rich side. If you run it excessive lean, the piston temperature may rise high enough to burn a hole in the piston and/or score the cylinder wall. Always use fresh fuel/mix. If you can't get non ethanol fuel, be sure to use containers that 100% seal to prevent the ethanol from absorbing water directly from the air.

If you can't release the switch from the panel you may need to remove the four mounting screws along the edge of the panel. See attached.

The system is not recognizing that you are in the seat for some reason. Ck the wiring from the switch could be broken/disconnected somewhere. plus read this fellows last reply.... https://lawnmowerforum.com/threads/husqvarna-z254f-dies-as-when-move-control-arm.66970/

There are a few potential reasons why your Kawasaki engine on your Husqvarna P-ZT 54 may be losing power when the blades engage. Here are a few possible causes and solutions:

Low engine speed: If the engine speed is too low, it may not be able to power the blades effectively. Try increasing the engine speed by adjusting the throttle.

Dull blades: Dull blades can put extra strain on the engine, causing it to lose power when the blades engage. Sharpen or replace the blades as necessary.

Belt tension: If the belt that drives the blades is loose or worn, it may slip when the blades engage, causing the engine to lose power. Check the belt tension and replace the belt if necessary.

Dirty air filter: A dirty air filter can restrict the airflow to the engine, causing it to lose power. Check and clean or replace the air filter as necessary.

Fuel issues: If the engine is not getting enough fuel, it may lose power when the blades engage. Check the fuel filter and make sure the fuel tank is clean and free of debris.

If none of these solutions work, it may be best to have a professional mechanic take a look at your mower to diagnose and fix the problem.

Here's a little info for you.... https://tractorproblems.com/husqvarna-foot-pedal-problems/ Best to you

Verify carburetor linkage and throttle shaft are not sticking (remove linkage as a test). The intake and carb assembly are several components. There can be no air leaks at any point downstream of the throttle plate. Check mounting screws are properly torqued. Could also be crankcase leak. Check fuel tank is not building pressure (remove/loosen fuel cap as a test).

If you have already replaced the flywheel, stator, and CDI, the next step would be to check the ignition coil and spark plug. It is possible that the ignition coil is faulty and needs to be replaced. Check the spark plug for any damage or wear and replace it if necessary. Additionally, make sure all the wiring connections are secure and free of corrosion. If none of these steps fix the issue, it may be best to take the bike to a mechanic or dealer for further diagnosis. They may be able to identify any other potential problems that could be causing the intermittent spark issue.

If your Husqvarna rz46i zero turn mower was acting like the transmission was slipping and now it won't move at all, there may be an issue with the transmission or drive belt. Here are a few things you can check:

1. Check the drive belt: Make sure the drive belt is properly attached and tensioned. If it's loose or damaged, it can cause slipping or failure to move. Replace the belt if necessary.
2. Check the transmission oil level: Low oil level in the transmission can cause slipping or failure to move. Check the oil level and add oil if necessary.
3. Check the transmission filter: A clogged transmission filter can cause the transmission to slip or fail to move. Replace the filter if it's dirty or clogged.
4. Check the transmission itself: If none of the above steps resolve the issue, there may be a problem with the transmission itself. It may be necessary to have a professional technician inspect and repair the transmission.

It's also possible that there could be an issue with the mower's hydrostatic transmission or drive system. If you're unsure of how to diagnose or repair the issue, it's best to contact a professional technician for assistance.

It's possible that the loose release switch could be causing the issue with the mower only running in reverse. When the release switch is not properly engaged or disengaged, it can cause the mower to think it is in neutral, which may prevent it from moving forward. You may want to try tightening or adjusting the switch to see if it helps. However, there could also be other issues with the transmission or drive system that are causing the problem, so it's important to thoroughly check all components and consult the manual or a professional if necessary.

If the engine mount set screw is not holding the engine in place and a new screw pushed out through the threads, it's possible that the threads on the engine or the screw are damaged. One solution could be to try tapping the mounting hole with a larger size tap to create new, tighter threads. Another option could be to use a thread repair kit, such as a helicoil, to create new threads in the mounting hole. It's also important to ensure that the screw being used is the correct size and type for the engine mount. Using the wrong size or type of screw can cause it to strip or push out through the threads. If the problem persists, it may be necessary to consult with a professional or the manufacturer for further assistance.

There could be several reasons why a Husqvarna K970 shuts down at full throttle after it warms up. Here are some possible causes:

1. Fuel system problems: The carburetor may be clogged or dirty, causing a fuel delivery problem. This can cause the engine to stall when it is running at full throttle.
2. Air filter problems: A dirty air filter can restrict the flow of air into the engine, causing it to run too rich and stall at full throttle.
3. Ignition system problems: A faulty ignition system can cause the engine to stall under load. This could be due to a failing spark plug or a bad ignition coil.
4. Overheating: The engine may be overheating, causing it to shut down when it reaches full throttle. This could be due to a cooling system problem or an issue with the engine itself.
5. Mechanical problems: There could be a problem with the engine or other mechanical components, such as the piston or crankshaft.

If you are not comfortable troubleshooting the problem yourself, it is best to take your K970 to a qualified service technician for diagnosis and repair.

To slow down the stitching speed on your Husqvarna Viking 18 x8, you can try the following steps:

1. Check the machine's manual: First, consult the manual that came with your Husqvarna Viking 18 x8 machine. The manual should have instructions on how to adjust the stitching speed.
2. Adjust the stitch length: One way to slow down the stitching speed is to adjust the stitch length. A shorter stitch length will slow down the machine's stitching speed. Refer to your machine's manual for instructions on how to adjust the stitch length.
3. Change the foot pressure: Another way to slow down the stitching speed is to change the foot pressure. Reducing the foot pressure can help slow down the machine's stitching speed. Again, refer to your machine's manual for instructions on how to adjust the foot pressure.
4. Use a different presser foot: Some presser feet are designed for slower stitching speeds. You can try using a different presser foot to slow down the machine's stitching speed.
5. Use a speed control pedal: Some machines come with a speed control pedal that allows you to adjust the machine's stitching speed. If your machine has a speed control pedal, try using it to slow down the stitching speed.

If none of these steps help slow down the stitching speed on your Husqvarna Viking 18 x8, you may need to contact a professional technician for assistance.

Once you've straightened it - you've finished the hard part. Now take the end without the pin and stick it into the hole located on the transmission frame (the metal piece that the transmission sits on.) It is directly under the seat. The hole is on the front side of the tranny frame. Once you have it all the way in, take the pin end and put it through the mower deck brace (right side.) There is a hole there also for this end. If it doesn't go through enough to get the washer and pin through, push the mower deck towards the anti-sway bar. It should give a lot since the anti-sway bar is off. Once you fasten it, your'e done!

I only know this because it just happened to me today. I have the same mower as you, so I thought I would share.

Check that the ignition module and the fuel solenoid remain powered when ignition switch returns to the RUN position.The mOOOoof sound is the leaf valve in the crankcase breather. As the engine spins down and the crankcase pressure drops, the leaf may resonate. Some do some don't.As a test you might try adding fuel (starter fluid, carb clean, or combustible brake clean). Remove the air filter and as it dies spray a shot of fluid into the carb throat. If it picks back up you know it's a fuel problem and not ignition.

If your Husqvarna backpack blower starts well but starts to act like it's not getting enough gas when you put it at 3/4 speed, there could be a few potential issues causing this problem. Some possible causes include:

1. A clogged fuel filter: The fuel filter is responsible for removing dirt and debris from the fuel before it reaches the carburetor. If the filter is clogged, it can restrict fuel flow and cause the engine to run poorly.
2. A clogged carburetor: The carburetor is responsible for mixing fuel and air to create the combustion that powers the engine. If the carburetor is clogged, it can restrict fuel flow and cause the engine to run poorly.
3. A dirty air filter: The air filter is responsible for removing dirt and debris from the air before it reaches the carburetor. If the filter is dirty, it can restrict airflow and cause the engine to run poorly.
4. A problem with the fuel line: If the fuel line is kinked, pinched, or has a leak, it can restrict fuel flow and cause the engine to run poorly.
5. A problem with the spark plug: A faulty spark plug can prevent the engine from running properly, it can cause misfire and the engine to run poorly.

It's recommended to check the fuel filter, carburetor, air filter, fuel line, and spark plug. Clean or replace them as necessary. It's important to consult the operator's manual for specific troubleshooting instructions and diagrams for your blower model, as the location and procedure may vary depending on the make and model. It's also important to consult the operator's manual for safety instructions, and to make sure you have the correct parts for your blower. It's recommended to seek the help of a qualified technician if you are not familiar with this process.
