View Full Version : 4-mix running bad
05-13-2007, 08:18 PM
Stihl fs100r trimmer with probably 60 hrs has been running poorly and starting hard after running. I noticed when I would fill the tank it runs good for awhile. It then seems to starve for fuel.Wont take throttle etc. I find if I remove and reinstall the gas cap it runs fine for awhile. Is this a bad cap? Anyone have this happen to them? Any thought are appreciated.Thanks.

Follow the directions from this past post and also repl the plug with a new NGK CMR6H.

Sounds like a classic symptom of a bad cap to me.
