Efco mt4100s chainsaw

Hi Guys.
I have an Efco mt4100s chainsaw. Having said that the symptoms
apply to any saw really. I have recently serviced this saw and
according to the customer it was running fine prior to me
servicing it. Now he has got it back and used it, he says it
starts and cuts fine for about 20 minutes and then it starts to
bog down in the cut and lacks power. I've had it in and factory
set the carb- again (slightly richened the L setting) and done
some test cuts and handed it back. Now it's come back again with
same issue. I have swapped over the module with a known good one
and re-checked the carb settings and changed the plug. What I
did find though, was the new fuel filter I fitted at the service
had become detached from the fuel line and is rolling around in
the bottom of the tank.....is it entirely possible this could be
the fault. After all, this is something I have done when I had
it in for service, and the guy did say it wasn't doing it
before????

It very well could be the issue. I would reattach the filter and
test run it for 20 minutes. Just to make sure that it is
repaired and not going to give him any more trouble.

How old is the saw? Could be crank seals.
