Maybe they should go back to giving honest horsepower ratings for their motors.
Now they just give a torque number.
But they do publish a torque curve with rpm data too so one can fairly easily calculate a horsepower.
My problem is that they don’t have altitude [and air cleaner element dirt level] compensated carburetors like one of the chain saw manufacturers [Husqvarna?] have.
Just try to get a larger engine. Gas is cheap.
