So I was trying to put a new head on my predator 212 which was originally for a 196cc clone (By the way, will this even work?) and while putting on the head bolts, I accidentally broke a head bolt off in the block I've tried everything to get it out with no luck, so now i'm just getting a new block. But before I do anything I need some info. First off, do I need to re-check the oil clearance with a plastigauge when putting it in the new block? Secondly, do I need a piston ring compressor to get it in? Thirdly, I only have a jeggs torque wrench with 1/2 drive which won't fit in the crankcase, so what should I do about torque on the rod bolts? Thanks for any help in advance.
