I have having problem with my Hysqvaran 125L with the pull cord. When i pulls cord, it not catching the trans and it sound like the spring is not catching?

need to open it up and check the springs and the bars for wear or damage

could be the pawl catch on the crank shaft is not working properly, if this is an easy start model, there are two springs and two pulleys to inspect. usually second spring is the problem.

Hi there. Firstly remove the end with the starter cord and make sure the fly wheel is opening when you pull the cord. If not lubricate it until it frees.If it is working then it could be just the carb gaskets need replacing or the worst case is that the piston is broke and may need sorting.

Flooding of the engine, over fueling. Put choke ing to off position. Check Spark. It may not be sparking therefore its not ignighting the fuel in the cylinder.

There are special tools made for this job, however not needed for most jobs (makes easier). Clean the spring and lube slightly with silicone spray or light oil. Catch the end of the spring that would be the outer end onto slot or pin and slowly spiral the coil into place holding down coils as you turn(dont try to coil the spring then drop it in, take your time as you wind and maybe ask a freind to lend a third hand if your fingers get tired, once you start you cant stop). The inner part of the coil has a bent hook that will catch on the inner portion of the pull rewind. Lood at how the rewind catches this hook by turning the rewind in the direction that it turns when you pull the rope. When you pull the rope it winds the spring. If you put the spring in backwards the rewind spring will not catch. Once you got the spring in place, turn the rewind in the direction that it turns when you pull the rope until it stops, then release one turn and insert rope thru guide and into spool to tie knot. Slowly let rewing pull in new rope. Good luck

I assume that you are speaking of a pull start mechanism.
I can not imagine how to put a put pull starter back on "wound tight". Your pulling on the cord tightens a spring which pulls the cord back in. They go back together with the cord fully wound onto the spool.
Usually, I only take these apart to replace the cord. Wind the new cord onto the spool without handle. Reassemble, then pull out on the cord a little when attaching the handle to the cord. This is the only way to get tension onto the spring at the fully retracted position because the catch for the spring is on the machine and the spring itself is on the underside what you are assembling.
If you do not wish to shorten the cord or replace it, then remove the handle, assemble enough to catch the spring, wind one turn tighter then feed rope through hole and reattach handle. Easier said than done.
If your spring is broken, then you will be needing a new one.
:o)

okay,after you have dissembled replace pull cord set aside now place the spring into the casing by catching the end into the retaining slot and wind it down into the casing hang onto to it now feed the cord end thru the hole afix handle onto cord then place into casing make sure that the spring and cord pulley dog together now holding pulley down in casing pull alittle cord out between case housing and pulley and preload spring by turning pulley around with cord 4 to 6 times secure pulley you should be all set good luck

Hi there take it easy
check the parts in link and order the damaged parts

good luck

yes exactly what i would do sounds like the springs are either worn or gummed up or just broken on the dog ears

sounds like the spring is broken itself.there should be a hook at one end and a loop at the other end.the hook usualy breaks off but the spring looks good.replace the spring with part number..4140 190 0600 ....that is the stihl part number.let me know if this helped you...if not give me a quick mail and i'll try to help some more......
