mbaum I especially like that pale yellow rubnblestone in the background that still seems to be on wheels ...

Flaminia floor panel

After the panel from underneath the rear seat had been removed half a year ago, I found the time to tackle that issue today. First attempt is to repair the original. Although “only” a floor panel there are a few challenges. Most difficult IMO is the s-shaped area with three folds back and forth. As I am using standard sheet metal, (no deep drawing quality) I thought the sheet would not make the various shrink and stretch operations. The Eckold turned out to be extremely useful for this job.











In order to keep things moving around the shop, eight tons of rubblestone have been delivered last week. They will make a nice rubble masonry.

Tedesco First of all I have to find out about the input element of the tester, say what is behind the black wire connected to the contact breaker. Most likely a transistor or IC followed by a simple circuit for switching the blue light at the back of the rotating aperture (blind? bezel?). Question is, will it survive a 12 Volt source for ignition and will it still work with 12V coming from outside?

Might be a good job for my brother in law to find a solution for that

Additional info:

Received an answer from the manufacturer, there is a LED in the rotating disk, no aperture. Only critical thing is to keep external voltage away from it´s input.

bmarler let your brother laugh, he's the one missing out. the old analog equipment works perfectly on the old cars it was designed for. i prefer it as well.
but i do confess, i have some diagnostic equipment for the modern stuff as well. it's impossible to diagnose can-bus without it. i think my biggest problem is i don't like the quality of workmanship i get if i have someone else work on my stuff. they never give it the level of detail that i do. so, if i have to do the work, i need the tools.
keep us posted if you add the high voltage to your tester and how you do it. i'll be interested to see how it works out.

Tedesco Sounds that your equipment is fairly complete! I like the idea of having everything at hand when needed. And btw, my brother in law who is an electrical engineer always laughs at me and makes jokes about the analog equipment I use, especially about the scope. He says there is modern equipment with pc interface for data processing, visualising graphs and I don´t know what.

Well there is, but not in my shop!!!

bmarler i agree, it shouldn't be hard at all. personally, i don't really need that as i have a good ignition scope to analyze the firing line. it's amazing how cheap those can be had as nobody wants to give up the garage space for them anymore.
but i can see the benefit of adding that to the distributor machine. i also have an old spark plug tester that would make a good companion to the distributor machine. there are actually 4 ports for plugs to fire under pressure so the entire distributor could be tested. cap,wires and all.

i may have to look into this small tester you have to add to my equipment.
Other than the old devices (often Bosch in this part of the world) the modern tester is not designed for testing the high voltage part of the ignition. I have contacted the manufacturer about this. As far as i can see it should not be a problem to add a coil and a couple of spark plugs.

PSk That will make such a difference to the drive-ability.

Flaminia distributor Marelli S82B



When checking the engine settings with the oscilloscope I frequently noticed that the ignition peaks of each cylinder did not perfectly line up. The first thought was a worn distributor shaft. After investigating a little bit about distributors, it turned out that a distributor test stand would be very helpful to evaluate the condition of a distributor, besides the fact that such a unit would add to the completion of my testing equipment.
Instead of searching for a vintage machine, which surely would have a nicer appearance, a small modern unit was acquired.
Took three Marellis from the shelf (2 S82B and one S102 for Flavia) and had a testing session.

A couple of the things that can be tested:

1. Advance curve

2. Dwell angle

3. Symmetry of ignition sparks

4. Vacuum advance curve





This is a four cylinder (Flavia)



Some additional items, adopters for different distributor shafts I made myself and attachments for electronic distributors





The first diagram shows a bad S82, the advance curve is far from factory spec and the sparking is roughly off line. The difference in angle on distributor between the earliest and the latest is 5°, that means 10° crankshaft.

The second one is much better although the dwell angle is out of spec (40°, should be 30°)

With a little practice one should be able to bring the distributor back to spec and in a next step optimizing should be rewarding.

PS revs are distributor, as are the angles measured, for crankshaft revs and angles have to be multipied by 2

Night life at "the Farm"

The blue Vignale is about to leave, my neighbor Marius is fumbling around on his big block and a distributor tester has arrived completing my analyzing equipment.








Many things to be done. Hot summer in the shop coming!

Brian,

thanks for your suggestion about the marine controler. In fact I am quite far from "boats" and the technical solutions to be found there. I have already checked on ebay, there are some for sale in the UK. But as you said, I have an idea of an analogue control lever using a modified pushrod clamp. Will report once it is presentable.

PS If you are interested in getting two twin Fulvia carbs synchronised in an unusual way have a look here (you may have to scroll down to "Terra incognita" again all in German, but the pics speak for themselves) Made a flow bench for the complete setup and adjusted the carbs on the workbench. The result is fantastic! http://www.lanciaclubdeutschland.de/index.html

Pete,

it has two camshafts, thus symmetric layout of the valve train.
