I'm out changing the plugs and wires right now.

Should I not start it up incase I foul out the plugs? Or should I give it a try and see if it fixes the miss?

Also can I pop off the front valve cover without having to remove that bracket that goes to the passenger side of the engine? Also what would I be looking for for the bad valve seals. Can I upload pics from my phone to show you guys?

The number 2 plug I pulled was wet and black and smelled like gas/ oil
