Need help with a Gas Trimmer

[Jim Bozdog]

I have a Ryobi 700r 2-Cycle Gas Trimmer with a Walbro 819 WT 454 carburetor and have not made any adjustments to the idle or high speed needles. I have rebuilt the carburetor, new plug, new filter, new gasket and replaced all fuel lines. It starts and runs at a reduced rpm on partial choke position only. Will run for five minutes then stops. Gas mix is new and correct. Any help would be appreciated.

Thanks

Jim

How to I remove theses plastic covers to clean under the idle and high speed mixture needles? Also I want to be sure to put them back to factory settings.

Make sure your muffler is not clogged with oil residue. You can get a large build up that will not allow the motor to "exhale" properly.

If the muffler is crimped together, just heat it till it stops smoking. I use a fish cooker.
