Hi folks,

I have a BG50 that starts and runs just fine for about 30 sec, then it slows down to about half speed. It still runs smoothly, just low rpm. I ran it without the spark arrestor but problem the same. Hopefully some ideas out there.

TAke the muffler off and see if hat makes a difference .
NOTE it will be very loud
After that try swapping the fuel filter .

While it is running, remove the air filter and see how it runs.
