I have a Weedeater Featherlite gas trimmer 18cc. It runs rough, and I have to use 3/4 choke throttle to keep it running. When I squeeze the trigger, it wants to stall out. I just put a brand new Walbro Carburator on it.:confused:

Try replacing the spark plug

Hi,
Check the spark arrestor screen in the muffler.
Peace,

Try replacing the spark plug

At the time of buying the carburator, I also bought a new plug.:o
