was just driving along friday the 13th when all this cr*p happened. put new coil and condensor and set timing and synchronized k-fish, etc.....but pulling 2 and 3 and no difference....and yes, they both have spark.....i'll set valves in the morning but i think i've got a blown H.G.......no smoke or anything but what else could it be? stuck valve in 2 cylinders at the same time? doubtful. will try comp. test later tomorrow.
