I am curious if the OP resolved his problem and what was the cause or fix.

Aoncurly,
You won't see or smell the gasoline because the leak is internal. And it would not affect the mixture, air leaks, etc. It would affect the residual fuel pressure that would cause problem during a warm start. If your mechanic is familiar with CIS troubleshooting, he could individually test the three (3) most common culprits. And if you want to know if your mechanic knows CIS, ask him 'what was the residual pressure after 20 mins. for the fuel accumulator, FP check valve, and PPV (primary pressure valve) respectively.
