PJC - Sounds like an amazing suggestion , I'll definitely give that a shot.
Richard, I changed the condenser and I'm going to take it for a test drive this weekend - as the likelihood of breaking down is high, I tend to need to put myself in a positive state of mind before heading out, that's why my updates are so infrequent.
I did blow air through the fuel line and I didn't see anything but petrol come out (I realize ,in hindsight, I should have put some kind of coffee filter in front to catch any sediment).
Coil is the next thing to try - after that, I'll drain the fuel tank to see if there's any water contamination. It's all good learning .
