Stihl BR600

[Billhook]

Following hot on the heels of Buffalo's thread.    (I am afraid I cannot come up with an answer to his problem)

I have had my BR600 for some time an it performs very well on a full tank of fuel, until the tank of fuel is half full, when it begins  to stutter and eventually stop.  This has been the case since it was brand new.  I know that I should have taken it back to the supplier some twenty miles away, but since I usually have had enough of it on my back after half a tank, I could not be bothered.  It seemed easier just to top it up with fuel rather than mess around taking things apart and maybe doing more harm.

Has anyone else had this problem, and is there a simple, cheap solution?

Have you tried just taking the fuel cap off and replacing? Could be tank breather not functioning so creates a vacuum in tank .

As above?

I’ve heard this before. Have you checked there is actually both fuel filters on the pipes in the tank (one either side of fuel tank) with pipes running of a “t”. The one I heard about didn’t have the filter on one side so when fuel was low the pipe floated to the top and stopped fuel getting through
