Re: Carb trouble

Many small parts in Weber carburettors are identical and used in several models.
Strange enough, this is not the case with the idle jets in DCN 40 and DCNF 40:

The original numbers are often shown as 74401. and 74405. (followed by the size
number, e.g. 055)

Re: Carb trouble

This "classic" hesitation is probably just depending on too small idle jets. To work well with our "modern" ethanolmixed fuel, the original 0.50 or 0.55 are too small. Try 0.60 or even 0.65 instead. That, and strong ignition sparks from a working Dinoplex or MSD ignition usually ...

Re: Unknown relay

It is the relay number 31, controlling the no-charge warning light, number 50.

In the electric wiring diagram, it is not shown placed-out as in reality!

Re: 2.0 Liter Stalling at Stops

Re your description, I would guess you have a fuel feed issue, rather than an ignition problem. Have you adjusted the fuel pressure through the FilterKing to feed the Webers with 0.25 Bar? Also, the Weber float level adjustment is of great importance. Note that DCN 40 and DCNF 40 have different reco...

Re: Ignition timing

As far as I remember, the red mark at the distributor housing is indicating ignition point for cylinder no 1. However, the 10 degree mark at the crankshaft pulley is for adjusting the ignition point at cylinder no 4! This 10 degree mark can also be used checking the ignition timing for "the oth...

PM problems

When other FDF members send me PMs, I earlier always have got an automatic sent e-mail from FDF that I have got a message waiting in my inbox. Nowadays this is not working. Why? For instance - by coincidence - I four days ago found a PM sent to me a month ago (!) without I have got any notices about...

Re: Installing a Dinoplex

The original 12 Volt feed for the Dinoplex is coming through the blue wire (out of the wire harness at the right inner wing). This should be connected to B+ at the ignition coil. The brown wire is feeding the rev counter, and should be connected to the D terminal at the ignition coil ballast resisto...

Re: 2.0 cam clearance buckets

Looking at the Spare parts Catalogues you will notice that not only the valve tappets were replaced when the valve shim system was changed, but also the actual valves. 2 litre Dino early valve tappets.png Dino 2 litre late valve tappets.png The valves outer diameter were slightly changed, but more i...

Magneti Marelli BZR 205A ignition coil

I spotted a discussion at the Forum re why the BZR 205A ignition coil has 3 connectors, instead of the "normal" 2 connectors. The special feature of this coil is that the primary and secondary windings are not sharing the same ground (earth) connections. Other "normal" ignition c...

Re: Restoring a 2.0L 67 Fiat Dino Spider

The Pininfarina emblems for a 2 Litre Spider were always placed at the front fenders. For the 2,4 Litre Spiders, FIAT moved them to the position at the rear fenders, between the doors and the rear wheel arches. In other words, they are mixed up on your car! No 2 Litre Spider had any padding undernea...
