I have heard allot of people talking about Ryobi engines from Harbor Freight. I checked with them and they have stopped selling them. Does anyone know a good source for used or rebuilt engines?
I have called my local lawn mower repair shops and they gave me some junkers for free or next to nothing, but they all need major work or are thet wrong configuration.

Where else can I get cheap deals or go factory direct?

I also have a poll question...
What is your favorite brand engine to use if you had your choice? Ryobi, Stihl, Echo, Homelite, Other?
