I used a new screw in type of gauge. I did remove all the spark plugs the batttery had a full charge etc. I started with the left rear came forward then to the right front and on to the back right. The first and last test cyl were the highest so the battery did hold up. No offense taken. I will pull the front of the engine off tomorrow and check the cam timing, but I don't see how the belt could jump the teeth and not show any damage.
