As the condensor is mentioned here a couple of times:

As Paul writes it is mounted to the distributor. The part number for the distributor is Ford 81SF 12100 BAA (at least on the 1984 model - the 3 letters might be different on yours)
Checking a condensor is typically done by measuring the resistance. I know how to do this older distributors where it can be removed - I wouldn't know how to do this on the Ford 81SF 12100 BAA

I also don't know when Ford/Morgan changed the distributor and the cabling from two wires to a 3 pin connector. There is a repair kit and it has the newer connector. Check on your car on how the distributor is connected to the coil.

Instead of the repair kit, it might be a better idea to replace the entire distributor. I got this one here: Ultra Automotive

The replacement unit has also as the 3 pin connector. Ford offered a cable for earlier XR3 that needed a new distributor: [Linked Image]
Part number Ford 84AG-12045-BA. This has the new 3 pin connector and a new one it is extremely hard to find.

Nevertheless - the venting issue that TBM notes, checking and cleaning the jets and AutoChoke should be done as well.
