I have a Stihl TS 700 concrete saw. It start an runs very good,but sometimes at highspeed it suddenly stops. Then I just can start it again without any problems and it runs good again. I have replaced airfilter,fuelfilter,sparkplug. Do someone have an idea what the problem can be.

If it is starting and not continuing to run it still sounds as though something is blocking the fuel flow. If the carb has been cleaned out, literally torn down and the needles cleaned so that no small debris is clogging them, check the fuel tank and lines for anything that could be restricting the flow to the engine. Remember that it's recommended that you replace the fuel line (cheap fix) when you dismantle the carb. Removing the line breaks off small pieces of the rubber in a worn line, which can re-block a freshly cleaned carb.

SOURCE: stihl line trimmer starts but won't stay running

check to make sure your kill switch is not shorting and you have the right gap from the coil to the flywheel also if the flywheel sheer pin is damaged in the least this will cause a multitude of problems... it is the timing pin and must be in good shape not damaged or sheered ..any way reply to [email protected] and i will try to help you through this.... DALE good luck and will wait for reply..

SOURCE: stihl bg 55 blower runs good for 5 min. then loses power

1) carburetor gaskets/diaphragms may need to be replaced

2) ignition coil may be breaking down when hot

3) check compression when cold, then after it stops, when hot

4) could have a vacuum/pressure leak

*I would investigate carb first

SOURCE: not getting spark when starting

[email protected] HI GRYDERT your problem could be your on, off switch. This might sound funny, but switch the on off switch real fast several times, then see if you havee fire. If not check your spark plug. If you have a n
ew one try it. If that don't work check the connection at the plug to be sure it is makiong contact with the plug. If all this does't work you will have to go inside to the coil. They don't usually go ba d but it could. But first check to be sure it isn't grounded at the small wire from the switch. Good Luck.

SOURCE: stihl ts 400 wont start

If there is good fuel in the tank and the plug gets wet with fuel, and there is a good spark stating the obvious it should go, if not there could be a mechanical issue, piston scored, rings worn etc,

Stihl ts 420 concrete saw screws will not come out to replace air filter


This was very common, they say it was because the screws were too long and prutruding through the nut the thread then gets covered in concrete dust and when trying to unscrew locks in the thread. You will probably have to destroy the cover to get it off.

Running bad with oil leaking out the muffler crimps. Too much oil in the mix? Cleaned the air filters already and checked the spark plug. Looks good, maybe the carb?


Check the spark arrestor screen and see if the screen has carbon deposits on it. If it does then you need to clean the spark arrestor screen and re install it in the muffler. You can clean it by burning off the carbon. The air filters on the TS 700 Cut Off Saw do not need to be cleaned, they only need to be replaced when the unit starts running poorly. The carburetor could have something in it that is keeping the needle from closing and flooding out the unit. I would suggest taking this unit to a Stihl dealer that has a Gold Certified Technician. You can use the dealer locator on the the Stihl USA website. I have included a link HERE. You can type in your zip code and it will tell you where the closest dealer is and what level of technician they have.
