Ryobi gas weed trimmer

[smiller]

I have just replaced the full lines. It starts great BUT...runs only a few minutes and dies. Is there a fuel filter? If yes, where?
It is a model #725R

Thanks

I too replaced fuel lines, starts OK, but won't stay running, keeping choke partally on helpd but still quits!
I also think I see "bubbles" in fuel tank!!
Is there somekind of a fuel check valve in the fuel circuit somewhere??
If you or anyone has help for a fix for me, please respond!!

Sorry to hear that your initial repair didn't work for you. Like Robert Gunns said, there is a fuel filter located in the fuel tank. You can usually bend a wire into a hook to fish the fuel line with the attached fuel filter out of the tank for replacing. It is a good idea to do a "tune up" yearly on all of your gas powered tools. A basic tune up would consist of replacing the air filter, fuel filter and spark plug. Doing this should greatly contribute to great running tools. The problem you described of starting but then dying a few minutes later sounds like dirt or other restrictions in the carburetor. You mentioned that you replaced the fuel lines. If there was a hole in the feed line in the tank it very likely pulled dirt from within the tank into the carburetor. By replacing the carburetor (part # 791-182875 ) you should have a great running trimmer again!

Good luck!
