253 wont start / run

[Wombat7051]

Ok so I fixed it.
1. Timing chain out by one link. Always remember it is dot to bright link not dot to dot and nine links apart
2. Quadrajets need vacuum to set idle screws, no vacuum no adjustment
3. Quadrajet adjustments and settings need to be done in gear in an auto or it will stall
4. Buy a vacuum gauge to set timing and mixture invaluable
5. Ran a relay and fitted the electronic distributor, it is much happier
All in all I learnt a lot from this experience. Now he has a car might move back on to the first van.

Thanks everyone for your help
