Greeting friends......Friday I picked up a couple of blowers from my friendly OPE repair shop. I usually check in there twice a month to take away their left behinds or "didn't want to spend the money to fixes".....one of which was a Toro 521. I asked the owner of the shop...what's wrong with it....he said "nothing". Well I took it home and he was right....nothing wrong with it. Very clean paint perfect, chrome like new...engine starts first pull...in general a sweet ride. So nice I was thinking of keeping it ..so I looked at it with the idea of doing an impeller mod......No word of a lie....there wasn't enough room between the impeller and the housing to put a business card! I've never seen a machine with this tight a tolerance. For some reason these machines don't bring any money on the used market...why I can't say....but I am totally impressed with the quality of this little engine that could!
