Anyone else got one of these? 
 
I recently bought a Stihl RM 248T and it’s been fantastic so far although I recently felt as if I needed to get it serviced. 
 
Took it out of the cellar last weekend and it sounded almost like it was mis firing. I had it serviced by the same place I bought it from to get it ready for spring, and they did a great job.
 
Just wondering everyone elses thoughts. 
 

Did you run it empty last year and now fill with fresh fuel?
 
Stale fuel WILL cause all kinds of running issues..

Hmm I'm unsure if it was completely empty, are you recommending it should be ran until complete 0? 

If being stored for a long time, I'd drain it.  
 
I don't know if you have Ethanol fuel over there but if so, it'll go bad usually around 2 months.
 
As of right now, I gather it has some old fuel in it.  DO NOT add fresh fuel to it, you'll just get more bad fuel in the tank.  
 
Dump, suck out, run all the old stuff out.  If you can, catch what comes out of the tank and inspect.
You'd be surprised sometimes what you'll find.
 
Put in fresh fuel, check the spark plug for cleanliness or replace with a known good one.
 
 
BTW, easily 90% of the machines I work on (mowers, small engines, chain saws, concrete saws, riders, etc), are what the issue is.
 
The smaller engines, with the small carbs go bad and clog up easily with varnish, water in the fuel, etc..

Thanks Scott I really appreciate this

Just for reference and these guys did me a solid. 
 
I just wouldn't want to keep going back to them with the same issues. Maybe I'm a complete dunce who knows
