Hey guys, I'm tearing my engine down to the core to replace a stripped counter shaft (hooray) but I'm stuck on getting the cylinder off the crank case. Usually a few taps with a rubber mallot around the circumfrence does the trick, but this one won't budge. Yes all of the bolts are removed (I've checked a hundred times). Tried using the block of wood technique. Even done the big no no of gently trying to pry it off. THING WILL NOT COME OFF! Any tricks I should try before I break out the dynamite? Thanks!
