I want to comfirm my fear. I recently finnished a complete overhaul and engine rebuild of a 1976 Ford 4600. After getting the engine to start for the first time the following happened:
1. I ran the engine for approximately 2 minutes and 24 seconds. It sounded beautifully right out of the gate.
2. At about 1 minutes and 30 seconds the noise of the engine changed. It more or less was sounding bogged down as if it had a load.
3. At about 2 minutes the noise changed again. Same as before, the noise sounded more bogged down. Then it quit at 2 minutes and 24 seconds.
4. Multiple attempts to restart have ended up with the engine starting, but then quitting within a few seconds. The engine sounded real tight as if it did have a load.
After working through all the theories and eliminating valve gap and fuel issues, I am thinking my timing is off. I am just trying to confirm this theory. Does that sound l;ike a correct assessment.
I checked and rechecked timing to the point where I am surprised the timing would be off, but this is the only logical conclusion to my problem. Thoughts?
