Your petrol-powered STIHL machine will not be used for more than 30 days? Regardless of whether it is a chainsaw, a cut-off machine or a brushcutter – the engine should be prepared for a longer break in use.
During storage, reactions of the individual fuel components can occur, which can lead to deposits in the carburettor and thus impair performance.
To avoid the resulting running problems, only two steps are necessary: Empty the fuel tank and run the carburettor dry.
In this video, we show you exactly how your machine is ready for use again even after a long rest period and how it can be reliably restarted.
For optimum performance, excellent engine lubrication and maximum cleanliness, we also recommend STIHL MotoMix. The premixed fuel without ethanol remains stable for a long time and can be stored for up to 5 years.

BG ethanol dryer works great as well.
Stihl sell a product called fuel stablizer (partnership with Sta-Bil) that prevents this problem. Keeps fuel good for 12-24 months
I've had a STIHL MS-261 C-M for some firewood cutting, but nowadays, once it starts, it runs like a champ, but once I squeeze the throttle it immediately chokes out and dies, despite having the starting steps done correctly, what should I do?
To much work.. all the machins runs every week 👍🏽👍🏽🍁🍁
Our stihl ms 160 chainsaw is just amazing.
I always use stihl moronic no problem it has a 2 year shelf life no ethanol it also has fuel stabilizer in it. When you dump out the fuel it dries out the fuel lines
The over engineered flip gas cap is why I use husky now. A gas cap does not need to have 17 parts.
in the west, we dont say petro. otherwise, I would share this to Facebook.
Stihl technician here. in my opinion when the operator do this its actualy worse. why? when you run the machine to empty the lines and carburetor its impossible to completly empty the carb and there will always stay the remeains of the fuel. In the period of 6months the lines, diaphragms and fuel filter becomes hard and it starts to break. its better to leave fuel inside and you empty the tank and replace with fresh mix when you need the machine again after long storage(1 to 6months). On the other side yes motomix is the best option.
I drain fuel yesturday
I always used Stihl motomix, never emptied the tank,it starts from the first or second pull in the spring.
I’ve been doing this for years and each machine starts right up after months of winter storage.
Stih HP ultra has fuel stabiliser? Can be stored for a long period in fuel mixture?
