Echo 7310 or husky 572

[Ryan'smilling]

I run 40:1 in everything. 35 should be no problem.

How heavy can you run the mix in an auto tune saw I have always just run 35:1.

I run 32:1 zero issues.

Minnesota Jon, you anywhere near Becker? I have a 572 you can try.

Too many rpm unloaded. Will kill the xt. Piston is too heavy.

The 572 and 372xt, pistons look to be of the same design. Does anyone know the weight of the pistons?

Old guy I am about an hour north of the twin cities. Do you like your 572?

 

[old guy]

We must be just about neighbors, 572 is a great saw, I have bars from 16'' to 28'' and a bunch of pine logs here, could probably find some oak too.
Come on over.

My Husky dealer and expert advises not to go heavier than 40:1 in the autotune saws as it can cause some issues in his experience. The saw computer is making some assumptions about fuel composition in its calculations.

I run 40:1 in 3 auto tunes, never a problem.
