open gas cap and see if it will run again. m,any times the gas tank vents clog and the engine can't draw gas after a few minutes.
another thought is the oil mixture.. 50:1 with oil made for air cooled engines....not boat engine oil

First try this... put some 30 weight oil in the plug hole aso much as you can until it reaches top of plug hole. Let it sit there a few days allowing the oil to creep between the walls and piston. .. then try turning the flywheel with a socket and ratchet, a little forward, a little the opposite...


Now, if that doesn't work, it depends on your unit... if we are talking about a $400 top model back packer, then it would be worth getting it repaired... you would be paying between 150 and 200... if the unit costarts 300 or less than buy a new one... period

Kill switch most likely has broken wire between switch and engine. When in "kill" position, it should connect the top of the sparkplug to the rest of the engine. If it doesn't, either the switch is bad or the wire is.

Internal or external snap rings usually require a special pair of pliers to remove. In absence, you might try a very pointed pair of needle nose pliers or even a pair of dental tools or similar. Once the ring begins to dislodge from its groove you should be able to work it out. Reinstallation might require the specific tool.

With todays gasoline it turns to what is called varnish very rapidly and more than likely some of the fuel that set in the carb over those 6 months has turned into a gummy varnish so the carb probably needs cleaned, If it is not to bad you can probably adjust the carb with the air/fuel mixture screws and keep it running well till end of the season, shouldn't take more than 1/8 to 1/4 turn though. I hope this helps

They are refering to the 'fuel primer bubble' located on the bottom of the carb.

The user manual usually describes the adjustment process fairly well and usually it works well on a new or nearly new machine but not so well on older machines. The typical carburettor has three screws being the throttle stop adjustment for the idle speed, a mixture screw for low speed and one for high speed - by the time a machine has aged enough to need adjustment, getting it right is nearly impossible and getting it near enough to do the work is the main aim.

From the position the screws were in when the machine last run well it is important to note 1/8th of a turn at a time is the sort of adjustment needed. Adjust the low speed screw for a reasonable idle and then up to working speed to adjust the other for smooth running, or at least that is the theory.
The trouble is adjustment of one screw has an effect on the other which means a deal of patience toing and froing between the screws until a balance is reached...

Carburetor setting should be done by a dealer and by using a tachometer. However, to get a ballpark setting. Turn the screws in until they lightly seat, then turn the "H" and "L" screws out 1 1/2 turn. Then have your local dealer finish setting the carb.

This video will show you how to adjust the air/fuel mixture and idle.

Husqvarna Garden | Answered on Aug 04, 2020


Carb idle mixture and idle speed adjustment might do the trick or it might need a carb stripdown and clean before readjustment. The carb diaphragm can be affected by long immersion in fuel and lose flexibility and in that case replacement is advised.

There is a small chance the vacuum pulse from the engine crankcase isn't strong enough to keep the carb supplied with fuel at low rpm.
This isn't unusual and usually happens when a 2-stroke engine has been idle for a while, such as over winter. It was running fine last season but now it simply won't behave.

In that scenario it is possible the crankshaft seals have lost flexibility and air is being drawn past them reducing crankcase vacuum...
