Help. Bx2660 has started to oscillate, run rough and lose power after it's warmed up. Acted up last use which was most of the day. Now within about 10 minutes. Starts and runs fine at first.

Just a WAG, but check the fuel cap to make sure the vent hole is open.

There have been issues for some, where as fuel is consumed a low pressure like a partial vacuum forms in the fuel tank, and fuel does not flow properly. Often simply running the tractor with the fuel cap loose can eliminate this possibility.

You could disconnect the fuel line at a convenient point close to the tank - perhaps the fuel filter. Ensure you get a good flow of fuel. Catch it in a container and see if you can get a steady stream for perhaps a quart, or even a liter. This will confirm your fuel flow. It's a starting point. Don't forget to follow the bleeding procedure after everything is reconnected. This is also a good time to check your air filter.

I will check that, thank you. I believe there was a vacuum when I opened it.

I filled the tank and added 2 1/2 oz of Diesel 911 and was able to finish the day but could still hear it struggle a bit. I'm going to check the breather on the cap and will check for fuel flow next. I checked the air cleaner and fluids right away. Thankx I think I'm going in the right direction now.

It was the fuel filter under the tractor. The people that sold it to me had told me filters were changed. Obvious to me only the one in engine compartment had been. They have lost my business.
