The clutch has a two wire flying lead. For the clutch to remain powered after disconnecting the cable at the clutch (blue/black) implies someone has modified the original factory wiring. See attachment.

Weak spark or no spark or spark at wrong time. Do not use a neon type spark tester as it will indicate spark when it is insufficient. Use an inline gap type tester.

To test for spark, compression, and timming, drain all the fuel, choke off and give the the starter several pulls. If the plug is wet, leave plug out and give it several pulls, reinstall plug and give it several pulls, then check plug. Repeat until all residual fuel is gone and plug remains dry.

Now that all fuel is gone you can use an alternative fuel, i.e. starter fluid, that won't flood the engine.

Air filter removed, hold throttle open and spray a 1 second burst directly down the carburetor throat, release throttle. Leave air filter off and promptly attempt to start, several pulls. If no fire then it's likely a spark or compression issue, not the carburetor.

If it fires and runs for a few seconds, then timing, compression, and spark are OK and carburetor remains suspect.

The symptoms are a operator not in seat.

The seat switch requires a normally closed switch that opens when seat occupied. See attach.

The problem is that the engine is a funny size at 40cc. If it was 50cc, you could get away with motorcycle rings. The normal way to size rings is by measuring the bore with an inside micrometer across left to right and then again front to back. The front to back measurement is often a little more worn. Then you order rings by diameter and thickness, Any local engineering company can do this and supply you with generic rings. There is a different model here with rings at $25 but Jack's Small Engines is $57. My advice is get the OEM ones. You will also need to hone the bore lightly to dull the polish. Oil the new rings with 2 stroke oil when fitting them. https://www.google.com/search?q=husqvarna+145bt+piston+rings+size ..

Any debris on top of the deck e.g. thumb sized mulch, driveway stones, pencil diameter sticks or larger. All may cut and snap a belt if they get wedged between the belt and any of the pulleys.

Any hard foreign object of the size that will jamb into a pulley v groove.

I answered this yesterday didn't I? I looks like someone deleted my answer because this is still on the main page even though it has been answered by me. It is a shame because the other Answer had diagrams and 3 videos.https://www.google.com/search?q=Husqvarna+model+21LCN+String+Trimmer.+Fuel+line+diagram

Did you have the problem before replacing the filter and lines? You may have a fuel blockage inside the tank. Make sure you have a good gas flow to the carb. Dirt or other material may be in the causing the carb float to let too much fuel in. A bad air filter will cause the carb to run rich. Possible a bad spark plug or the spark is weak to the plug.

Page 27 here shows what looks like a standard size CD Disc. Does yours have this? If it does, you just need a CD Clean Disc. It has little brushes that clean the optics of dust. https://media.rainpos.com/3849/megaquilt_18_qbot_setup.pdf https://www.amazon.ca/cd-cleaner/s?k=cd+cleaner ....

The start solenoid control side winding has two conductors, WHT and BLK. BLK is the return to battery negative. WHT is fed fused battery positive from the ignition switch through the PTO switch thru Brake switch.

Suggest you use the volt meter referenced directly to the battery negative post or clamp. Probe the ignition switch "S" contact WHT wire. With switch in START position the S contact must be battery positive which in turn means the WHT wire must be batt pos. Then follow the WHT wires to/thru the PTO switch, to/thru Brake switch, to solenoid.

To recognize the 3D programmable card on the Husqvarna Rose sewing machine, you need to select the corresponding design number on the machine. The design number is usually located on the packaging of the 3D programmable card or in the software used to transfer designs to the card. Once you have identified the design number, enter it into the sewing machine using the keypad or touch screen. I want to let you know that not all Husqvarna Rose models are compatible with 3D programmable cards. Check your machine's manual or contact Husqvarna customer support for more information.

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.

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/

Ken here's a parts diagram... https://www.jackssmallengines.com/jacks-parts-lookup/manufacturer/husqvarna/tractors-ride-mowers/yth22v46-96043016100-2012-09/drive It appears there is only 1 linkage rod (part 163) back to the hydro trany. I'm wondering if it is low on fluid or freewheel control in "half engaged" position. here's the manual.... https://www.manualslib.com/manual/74464/Husqvarna-Owner-S-Yth22v46.html?page=20#manual Best to you.

Disconnect the kill wire at the ignition module (coil). If you then have spark, then likely the kill wire is shorted to metal somewhere along its length.
