Unit was defective when bought

  • Really Easy
  • 1- 2 hours
I ended up having to also replace the crankshaft bearing well as the cylinder kit. The owner thought the knocking was too much oil which led to a scori g of the cylinder when it needed crank bearing replaced. Sorry Huskvarna the first one wouldn't weedeat this was the second.
