Yep, it's about my limit too, very glad when I get one rested on the bench. As for 750 motors, 180lbs is way beyond me so last time I got my mate over to help, he usually works on plant, diggers & stuff. I turned my back for a moment & he said "well where's it going then?", looked round & he was stood there holding it in his arms, like it was nothing. He must eat loads of spinach.
