    cutting out on acceleration problem is definitely a carb issue

If you have over 200 hours on this FS 80 then you may need a valve adjustment(yes this 2-stroke has valves). if you wanna try to do it yourself it should be set @ 0.1mm @TopDeadCenter. my advice is take it to any stihl dealer and let them do it. its scheduled maintenance

Stilt fs85 cannot start, what may be the cause of it?


First check your muffler's spark arrestor to see if it is clogged.

If not clogged try adding a little fuel mix introduced into the carburetor throat. If starts then you have carb problems.

If it don't start then you may either a compression problem or ignition problem.

Your dealer is right. Gas is not a carbs best friend. every time you fuel dirt gets in the fuel tank from the air. This eventually blocks air and fuel passages and check valves inside the carb. That is the reason. Carbs wear out like anything else. Check the price of a carb compared to a kit. Some Stihl carbs are reasonable.

You did not indicate whether or not you have compression now that you have changed out the gaskets and piston rings. If not, it seems to me that the problem could be a) cracked head or block, b) bad valve(s) or even c) a warped head.

Sorry for the bad news (if I am right).

I can't get my blower to accelerate. It will only idol on full choke. If you pull trigger it bogs down. I replaced the fuel line and sprayed carb out.


Check the following, and then clean or replace:
  • Fuel Filter - Located INSIDE the Fuel Tank
  • Spark Plug
  • Spark Arrestor - at muffler
  • Carburetor - May need a rebuild kit
Watch this as well...

I'd put my money on it being the actual carb body. The carb body its self contains a couple of small valves which can get blocked or damaged and are practically impossible to replace. Look for a second hand OEM carb and if needed use your rebuild kit on it. That would be the cheapest route

Blower bogs down and kills at full throttle


Check the following, then clean or replace:
  • Fuel Filter - Located IN the fuel tank
  • Spark Plug
  • Spark Arrestor - at muffler port, creates resistance of exhaust flow, engine then bogs
  • Carburetor - may need a rebuild kit
Then watch this...

Assuming everything is back toether properly and was not the problem the frst place, remove the exhaust pipe to expose the exhaust ports to ensure they are not carbon block. Also check the exhaust it self for a spark arrestor screen that could hve been carbon fouled and clogged. Cannot free flow because of the problems noted above, you will not be able to run a two-stroke engine reliably.

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.
