I am brand new to this conversion thing and despite reading most of the threads I have not seen how to completely take one of these engines apart. I have a Ryobi 31cc and a Poulan 32cc that I took out of trimmers that had other problems and was not worth the effort or money to make right. I have both of these engines broke down but can not figure out how to get the crankshafts out so I can do a bearing replacement after a anti freeze bath in a crock pot. I am sure this is something that is simple but is something that I have never done. I would appreciate it if anyone would chime in here and let me know how this is done. I am basically dumber than a can of rocks on this one. Thanks in advance.
