What would you like to know? It is a pretty normal progressive system where the softer spring controls the advance til 2000 RPM. When the shorter spring makes contact, the other spring makes contact and they reduce the increse of advance curve together. It is impossible to make it perfect, but it di...

Hmmm, doesn't really look like a too hard a part to re-manufacture by simple hand tools; drill, file and a hammer. This is why I love hand built cars; they are quite easy to repair as hands haven't changed that much in 50 years.

Best wishes, Kare

When Francois and I test and tune a car, we try our best to get it to run right as quickly as we can understanding that most of our customers would freak from the time it sometimes takes to get a car PERFECT! The same goes for everything else on these cars from fitting trim pieces to getting the pa...

Different systems are slightly different. Ferrari used Marelli BZR201 coils with 1.5 ohm resistors. Fiat 125 used a BZR202 with a 0.8 ohm resistor. At top revs Ferrari distributor handles about double amount of sparks (6 vs. 4 cyl per distributor and higher revs), so slightly different parameters in...

Not sure why they did that, but it may have had to do with the different stresses you would get from a seat vs. the flex on the bottom of the car. The prevent the structure from bending out and resonating. To get an idea about the forces applied, you should remember that the difference in air flow ...

Visited an older Fiat enthusiasts today, among life in general we talked about ignition switches. He was well aware that some load must must be taken off from the ignition switch if you want the blades to last.

And - heh - that relay is a "Mixo", not a "Marchal". I think I've seen those in Citroëns.

I have trouble remembering how the ignition switch is connected, but I think the toasted blade is the main feed (battery plus), which connects over to two other blades when key is turned 2x90 degrees and finally to starter circuit on the back when the key is pushed. The blade gets burned as there is...

Two years ago I contacted Cicognani and asked if they could take all the parts I needed for my GTE and deliver them to me when I come to Auto e Moto d'Epoca in Padua. Being me, I of course sent the inquiry as I was leaving for the airport. To my great surprice they brought everything neatly packed a...

Oh, I thought "Giovanni" was in Italy. But you can always go to Ebay. See item 350371551272 for example. I'm sure that would fit as the boot is stretched over two terminals on the starter.

Go to any junkyard and pull one out of any Fiat.

Your picture nicely shows how the original labels were sinked into the structure of the tube and not glued on top of it. That was the fuction of the sticker too; to make sure that the customer really got the quality product he was paying for and not just some tube with a fake id painted/glued on top...

It says Alfa Gomma. That is a pretty well known company.

The big buckle in Pininfarina's GTE is just an ordinary belt from the 60's. At least Klippan used this mechanism type and the jaws biten into a bar that is installed over the transmission tunnel. These were usually solid belts without a reel so they would just lie on the floor when not in use.

There are two screwholes in each fixing points to mount a special bracket. Tom's has likely been drilled to take a single screw, and this would probably have resulted in a failure in case of an accident. The bracket was designed so that the bolts align with the pull of the belt, so the rear bolt is ...
