My stihl saw ts410 runs ok but as soon as you come to rev it ,it cuts out can you help


try setting your carb, you will see three holes at the side of the machine nr to the fuel cap. the one at the bottom screw it in as far as it will go then unscrew it 4 turns, the one above it do the same again but unscrew it one and a half turns, if this dont work its possible draging air in from somwere ie, crank seals, inpluse pipe, gaskets. it will need to be presure tested.

Can somebody send me a wiring diagram


You may need to wire a switch to the cut out. Since you "eliminated" it, its not going to rev. You need a closed circuit and should be able to create one via a switch, however I recommend consulting a local mechanic or other Fixya expert for a second opinion.

Hi, Anonymous and the usual suspects are:
1. Severely drained or faulty battery.

4. Clogged air filter or exhaust.
5. Cracked or incorrect float level.
6. Float needle is not seating.

My bike will idel but won t rev. just cuts off


Starving for fuel.
Make sure carbs are getting fuel.
Make sure fuel filters are clean,
make sure fuel pump is working.

If carbs are getting fuel but wont rev, you need to clean your carbs because your jets are clogged

Engine cuts out and sputters at 4000 rpm. sometimes hard starting. Quad 4


cutting out and sputtering at 4000 rpms are normal, its the rev limiter kicking in, all of them do it, as far as hard starting, is it just sense its been cold?? might want to put some fuel stabilizer in it.

When braking the engine revs reduce so far that the engine cuts out, it starts with a little difficulty but runs a little unevenly, revs dipping. It is possible to drive and behaves itself at speed but...


Sounds like an air filter cloged or a vacume leak. Check your air filter, and look at all the small hoses for rot or a break in them. Pulling in too much air will cause this also, ie vacume leak.
