.........when trying to start and get the timing right on your newly rebuilt engine it REALLY helps to hook up the vacuum line from the brake booster. I was only reading 5 on my vacuum meter yesterday. I didn't mess with it at all today because I owed my 2-year old some dad time. Sitting here I had an epiphany and ran out to the truck with a flashlight and found the hose laying free at the back of the carb. Massive vacuum leak found!! First thing after work tomorrow I will hook it up and get it timed.
