Hey Bruce and drunkees,
Thats great advice, I had the same prob when I had my Ryobi and that fixed the prob (with a good tune up as well) unfortunately the flex drive(upper) broke soon after ($86 to repair and then broke again)

......Next stop was the bin!!

drunkees, I hope you have better luck with yours!!

Kindest Regards, Darryl

to more Beers!!
