2 cycle oil has improved much since then. I will add some pictures when cutting big wood. I am blown away on the performance of this saw. No spark plugs to clean or replace. I have their line trimmer and pole saw.

Sun Joe SWJ701E Final Thoughts
"Very reliable start up."
And as I said, I don't front as an expert. Be sure to grease the end of the bar. I then cut some major limbs off a birch tree. No problems with power, or stalling. Starts very quickly usually after 2 pulls.
