String Trimmer Overheating
I have been using this Troy Bilt 4-cycle straight shaft trimmer from about 2 years, changed oil twice a season. It worked very till recently - now its overheating like crazy. I checked spark plug, carb, muffler everything looks good. It still runs well, just that it gets super hot in 3 minutes of use.
Which part is the most likely culprit ?
Will it be permanently damaged if I continue use it ?
Thanks in advance - DR.
