Ran out of gas in the middle of mowing (2 year old Troy Bilt). Refilled gas tank but when I went to pull the cord it pulled a few inches and got stuck. I unscrewed the top and the cord and recoil unit worked fine by itself. Doing some reading some have mentioned the possibility of a bad engine brake. Does this sound like a possibility ? Would this fix be better to take to professional or could be handled at house for a fairly inexperienced mower mechanic? :biggrin:Thanks for any help!
