I don't like mine...
So it's been replaced ... trying a new 55ax
I've had very good luck with OS 46 fx and 61 fx in the past...

I really feel my SX is a lemon..... Out of the thousands they make there has to be a bad apple in the bunch.. lol

I'll let you know how the 55ax does.... if it runs bad then it would have to be tank position

Thank
Ron
