Wow bob, thats a heck of alot of information, Thanks for that, rather informative. Well when I go to start it the plate makes a scraping noise underneath. There is a bit of movement between the rectangle washer maybe 1-2mm and the crank (should this be a snug fit?) maybe it just needs a new washer? Seems like a bloddy big hasstle to get a plate the same diameter. The blade is all intact not cracked or anything.
