Compression test revealed 100 psi on both cylinders. Motor ran but fogged the whole neighborhood with a cloud of white smoke for 5 minutes straight. Oil dripping out the 2 into 1 exhaust. Bad rings or valves or both? Either way, it looks like the top end has to come off which means I might as well hone and put new rings and seals right?
