I have noticed that my new 460 has been running worse and I know it needs the valves adjusted a little(slight chattering) but would the oil from the coil cause this?? It recently started backfiring out the carb and exhaust and for the second time I have found oil from the coil when removing the coil wire...and its a pretty good amount of oil...splattered all over the fender well and its still full inside the top of the coil. I have an msd ignition with a flamethrower II coil. Is it time to replace the coil? Also what color should the oil be inside the coil? The stuff I have coming from mine is slightly greenish/clear.
