I have a 10yr old weedeater with a Walbro carb, much the same engine as on my GS Warbird. Ten years ago I yanked the cord and fired it up...
Ten years later I yanked the cord and fired it up. Now, when I go after the weeds, this puts a load on the engine.. sometime it's hot and humid, sometimes cool and dry... Far as I can tell, it runs just the same as ten years ago....
Now, how did those fellas know how to set that carb for my ten year run? Did they check for sag in the high weeds??
