Some of these symptoms are consistent with water in the gas, so I would 
get the overflow hose fixed before water in there damages the FI components.

On a mosiac engine setup like this it is important to know EXACTLY what 
you have there for a FI system. I'd like to know which of the following you 
have: ECU, distributor, vacuum advance, pressure sensor. 

I note that 5 ATDC is the 72 timing setting, but it only works if you have the 
72 distributor with both vacuum advance and retard AND the 72 intake air 
distributor AND if everything is fully functioning. If you have a complete 72 
system, then note that only the Bentley manual includes the correct timing 
proceedure for that unique year.
