Sorry for the delay guys!
I ran my compression tester on each cylinder and they were fine. So I then repalced my expensive bosch plugs with cheap auto lights, adjusted my timing and the problem has not occured aqain. I did not feel comfortable pouring water down my carb. I have ran the truck hard a couple of times and so far so good.
Now can you guys look at my new post "Timing my Truck" and see if you can help me out there!
