I just bought a Black and Decker CS1030L. When I first started the saw, sparks starting flying from the blade guard. I immediately stopped the saw, reinstalled the blade, and tried again. It was still sparking. I am new to circular saws and was wondering if perhaps this was normal behavior. Is it possible installed the blade off-center twice??

I own a 3 year old Murray pull-start lawn mower and, of course, the pull-string broke today. I removed the sealed coil spring housing and began to wind the coil spring so that it would pull the reattached string (assuming I was going to be able to reattach the string) back into the housing when the piece slipped out of my hand resulting in the coil spring unwinding. Now I can't get the coil spring to catch; as I turn the piece I get no resistance. It spins freely. Does anyone know how to fix this without replacing the entire (expensive looking) housing? Thanks.
