Yes, a block is pretty cheap.So here is my dilemma. I took apart my clone and the cylinder wall was nasty looking. I'm trying to figure out the most economical way to put a motor back together. I have a stock predator (old style) that I could take apart. But it sounds like most of my blue lifan parts will not fit i.e. Cam, arc rod. The other option is to buy a new clone block. I guess the cheap way is to buy a new block???
