I picked up the 2019 Stihl paper catalog and seen the old Ht131 listed but no Ht 133. They still show the ht103. I have read many reviews on the ht133 and there were alot of complains on the shafts and plastic head. Was the stronger motor on the 133 to much for the new design? Wonder if this is temporary why they fix the problems with the ht133 or they did stihl give up on it.
