I disassembled , cleaned put back together ....same issue idle rough, no power or high rpm. Stalls when going to cut.....

Was the stored gas, everything............. cars, lawnmower, weedeater(4cycle) , generator, compressor, welder all runs fine......But the Stihl chainsaw and also a poulan chainsaw all had the same issues ........Fresh fuel cured the issues..........

Apparently the octane degrades enough in storage to affect the gasoline when mixed with oil it becomes useless.........

Thoughts............

you can get fuel additive to help it run or get a can of ether your 2 cycle motors will run fine once they run for a little they have to be warmed up some it allows the choke to open up. my boat motor runs like crap for a little while till it gets warmed up its because carbuerated motors aren't really meant for ethanol especially older models. but once you get em going they will be just fine. ether is a miracle worker for all motors just spray a couple of squirts to get it going don't soak it it will eat away at your gaskets this will allow the carburetion process to start with the air pulling across the fuel nozzle.
