Maybe, depends on if the carbs are FUBARed.
As far as compression goes, Depending on the unit, be it a chain saw or a trimmer, 110+ is great.
But, and this is my opinion, any thing over 90 that starts is good.
One of our 026 Stihl chains saws only has 90 psi, it will start on the 1st or 2 nd pull, it is 12 years old.....
