Messed up- Real time help needed -Distributor o-ring replaced. Now won't start. Pulled the distributor to replace the o-ring. Making sure to mark off so that the distributor is oriented the same way when put back. I'm guessing somehow I put back with the gear a tooth off (or more). Now the vehicle won't start at all. It was running just fine before I did all this. What's my next step. Need to get it running before this evening. Man, I messed up.
