Hi, See Data sheet attached.
Chris

Excellent Chris, any chance of posting info from this data sheet. I for one have spent time trying to get things working properly. I have checked jet/ emulsion tube/ choke sizes etc. against info in my LMC workshop manual reprint. With my existing Solex, there is no positive 'stop' for the cold start device, although I think I have it correct with no whistling/frosting at the orifice. Richard

Many thanks Chris, I haven't seen this particular sheet before in my service literature. I will translate to english text for quick reference.

Many thanks Charles. I will have a look on a full size screen and print. Richard

Can I double check, this 18mm) distance is the measurement between fuel level and the machined top of float chamber body- not including the top casting (lid) where the needle jet is located?
Thanks Chris

That’s it.....”distance N is always intended from upper edge of the float chamber, gasket excluded, with tolerance of +/-1mm”.

I see it now, at the bottom of the 'close up'. What does the 'N' actually stand for, anybody? Richard

Someone mentioned that the lid needs to be on the float chamber to measure the fuel level. Why is this?

Also, I've noticed that I've got a small outlet (hole) in one of my the chokes. It's covered by the choke valve when it's closed.
It's about 1mm diameter. I get a lot more carbon deposits in the side's exhaust tail pipe. See hole in picture attached.

"Distance N mm" is the heading of the column that gives the measurement for each type of carburettor.

I’m not that familiar with the Solex single, as my car has the Solex triple P3 1/2. On the latter, the carb lid has to be in place because the float “needle valves” are mounted on it. It is the position of the float that acts on the needle valves that causes them to shut, hence resulting in a particular fuel level. i.e. if the float closes the valves earlier, the fuel level will be lower, and vice versa.

If the inlet manifold is anything like a 3B manifold, it consists of a plenum chamber. So fuel/air from either of the 2 chokes (or 3 in my case) can feed any cylinder. So more soot in one exhaust pipe than the other is unlikely to be caused by the carb.......I think???

I think the PAAI has one common float chamber, but one idle and main cicuit per cylinder bank. And one common cold start device. Richard

Just in case its of interest to a single carb Flaminia owner, my inlet manifold is separated down the middle, as far as I could see and feel.
