I drain after each day even if using it the next day. If I'm not using for a while then I will run them - which I did not do last time, and so my G372xp currently has some minor carb issues.

 

If fuel mix is stored in a gallon can in a dark cold area, it'll be ok for a few months in winter. Dont leave it in the saw.

 

I got some cheap fuel/oil caps off amazon and drilled them out (carbide burr, a drill will go sideways), ideal for draining without making a mess.

A little dirt wont matter, all tools should have filters.

If the dirt gets excessive, a coffee filter works well.

Your mental !

I don't want to jinx my luck nor dismiss others advice but I have never had any long term storage regime.

Sometimes the tools run out of petrol sometimes they are left with fuel in. 2 stroke or 4 stroke gets left in cans or fuel tanks for months before getting used.

I have never had a problem with any chainsaw, strimmer, or anything with a 4 stroke engine with fuel left in it for months on end as a result. Doesn't matter if it is an expensive Husky/Stihl or a cheap Chinese Loncin. They all start when asked and run fine. My Stihl strimmer can go nearly 12 months without use but it will still start and run on the fuel in the tank if it hasn't leaked or evaporated. 

The fuel in my can was probably mixed 3 months ago or more but it will run whatever I put it in.

 

Not claiming it is best practice by any means but I can only think of one instance when fuel "went off" and that was probably many years old rather than months.

Well that sorted it then didn't it. Not sure why I got so many MS880s in that had gone pop. I always put it down to the fact that they had been left on the shelf for months with half a tank of fuel in them and then used again for a big cut and seized. Must have been coincidence:hmmmm2:

You may get away with it on strimmers or trimmers due to them revving less and not being under heavy load but try it with a decent pro saw having been left for 6 months and go in to a large continuous cut and your luck may well run out. An expensive test.

I always put many seizures down to a possible number of factors, perhaps old fuel, slightly lean, perhaps a slight air leak and probably a longer cut...it happens, I would show you a large bucket of seized pistons but they are long gone.

Nothing personal but all my old fuel goes in a mower or chipper and this discussion is similar to the fella that said chainsaw clutches cant spin off if you leave the side cover off!!

Apart from the fuel I try to give my small machines a run every month or so, the ones that are not heavily used won't have an effect on lifespan to all purposes, and the ones I use all the time are used at least once a month anyway. Then empty the fuel (actually, usually half a tank in the first, emptied into the 2nd and so on). Had a few second hand machines, never used for years that take a bit of work to start up, I find this helps.

Actually I am starting to get converted, tried Motomix in my hedge trimmer and didn't stink of fumes at the end of the job. Less convinced the saws make me stink as the exhaust blows away more, especially up the tree.

 

I work mostly on my own, but I've been subbing 2 days a week for someone a few months now. The fumes of other people's saws, after breathing nothing but Aspen for a while... it's a shock.
