The "rarely used" is the clue to the most likely problem, which is a build-up of "gum" and "varnish" in the VERY TINY passages [called "GALLERIES"] INSIDE your carb. This goo can block some, or all, of the galleries, rendering the carb useless. Fresh fuel is 'too little too late!" The "fix" for this problem is one of three things: 1. Replace the carb [way too expensive], or 2. Remove and overhaul the carb [kind of expensive, and definitely not much fun!]. 3. Try one of the relatively new "in-the-tank" solvent cleaning kits sold at most automotive parts stores. IF you go with solution number 3, BE SURE to follow the label instructions "to the letter"!!!!! The prevention of this problem is to never leave fuel in the tank, and thus the carb, for prolonged periods, especially over the off season!!!!! When not expecting to use the machine for a couple of months or more, drain all the fuel from the tank, and then RUN the engine until it "quits," indicating NO MORE FUEL in the carb.

This can be caused by several things, old or cracked fuel line, cloged fuel pickup filter, dirty carb or week diaphrams in the carb. It is my experiance with these if one goes the others are sure to follow quickly so I would suggest replacing the lines, filter, plug and put a rebuild kit in the carb. I hope this helps If you need further help, I’m available over the phone at https://www.6ya.com/expert/steve_f5a6ca85b5d1ffc9

Most likely a fueling issue, check fuel lines are not damaged, clean and service carb.

why, just fill tank

Your seat safety switch is not working. If the seat switch isn't activated, ie. a person sitting on the seat, the safety system will stop the engine when the levers are engaged. There is probably only one lever safety switch, on the right lever, which is why the left one doesn't kill the engine. Check the seat switch continuity and the wiring for loose connections.

Question edited for a lot more clarity! The throttle return spring has broken or come unattached. more here https://www.google.com/search?q=Husqvarna+RZ46i+runs+full+throttle ..

Likely there is air trapped in the system. Try raising drive wheels (safely) off the ground and operating forwards backwards. With minimal load on the hydo pump and motor, the air should purge.

The flywheel key has likely sheared. Contemporary utility 2-cycle flywheel keys are integrated into the flywheel. A new flywheel will be likely be required.

Question edited for clarity and typo botton to bottom. It should be at the top of the stroke. It is called TDC or Top Dead Centre and is then the spark ignites the fuel and air to force the rotation onwards in the same rotation as travel.

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 ..
