Does a 2001 ford bantam 1.3 (carburetor model) have a timing belt or chain?

Here is a pic of the model in Question.

This Bantam has a Mazda B3 engine and has a Cam belt that should be changed every 100,000Km

These B3 Engines normally run a bit rich on the fuel mixture. I had 323 1300 cars with the same engine. The tune-up specs for the best fuel consumption on these engines are : Ignition timing at 12 Deg, NGK BP5ES Plugs with a 1mm gap. The Main jets are normally 91 on the 1st Choke and 156 on the second choke. I changed mine using Weber Main jets. 85 Main for 1st Choke and 140 second choke. Thee CO on RPM is still well within Spec and better performance and a good fuel consumption.
