Fulvia / Re: Running velocity stacks/trumpets on a Fulvia

« Last post by Scott on 06 November, 2026, 11:35:38 PM »

Your topic rang a bell to a post many years ago when I was thinking along the same lines as you.
I've located it here: https://forum.lanciamc.co.uk/index.php?topic=657

I've stuck with the standard airbox and filter!

Lambda / Re: Tappet settings

« Last post by davidwheeler on 06 November, 2026, 08:48:48 PM »

To answer my own question - the greater expansion of the alloy block will lift the tappets away from the valve stem thus increasing the clearance.
D'oh is the exprression I need I think.
However, with the new bronze gear installed the valve gear is much quieter than before and sorting the cam follower bearings must have helped as well.

Aurelia / B10 bonnet release

« Last post by brian on 06 November, 2026, 03:54:34 PM »

I am being dim!
The cable has broken somewhere within the engine bay. How do I get in there to replace it?
I thought I would get the grill off to get at the catch but it is all in front of the radiator and I cannot see release clips for the grill.
What do I do?

Lambda / Tappet settings

« Last post by davidwheeler on 05 November, 2026, 09:37:00 PM »

Having re-assembled Sheila's top end, I set the tappet clearances to 6thou and 8 thou as it says in The Book.   However, the coefficient of expansion of aluminium as about three times greater than cast iron so I am wondering if I should set them to 8 and 10 thou?

Hi all
Fair bit done and my list of 12 things to do has been slimmed down to 3 and a halfish. To date we have fitted both exhaust downpipes and connected them up to the centre sections, the dynator is back in, the oil cooler and pipes are in with a new rubber mounting, the new steering damper is back in after a false alarm over a rubber bush that had pulled off the steel sleeve, the water pump pulley lock tabs are done and I have spent the afternoon making a tool to let me prime the oil pump.
To do is getting the rad re-cored, fitting the carbs and fuel line, setting up the ignition and prime the oil pump.

Fulvia / Running velocity stacks/trumpets on a Fulvia

« Last post by MLA on 05 November, 2026, 12:17:57 PM »

The other day after fiddling with the Solex carbs on our 1972 Lancia Fulvia Sport 1600 I ran it up the road for a test.  The air filter was off.  The induction sound was glorious. The little dear has never been on a dirt road and annual mileage is under 2000 miles.  This leads me to the question, what are the pluses and minuses of running velocity stacks/trumpets on a street Fulvia?  Pieces Fulvia  and a US Lancia parts supplier both have trumpet/horn kits for the 42ddhf carbs.
Experience or thoughts on the subject would be appreciated.

Fulvia / Re: Setting 1600 float levels

« Last post by Simon B on 04 November, 2026, 07:51:41 PM »

The technical data I think for all PHH carbs used on the Fulvia quotes a fuel level of 19mm plus or minus 1mm. The datum is the top surface of the lower carb casting. When measuring using the hole for the emission tube, later carbs have a brass insert which the emission tube screws into, if your carb is this type you need to allow an extra 2mm because the insert protrudes above the casting by 2mm, so 21mm plus or minus 1mm. From practical experience it sounds like Tim has found his car will tolerate a higher fuel level without problems. I would think the 17mm quoted though is from the surface of the casting rather than the top of the bush.

A float gauge will only get you so far as I suspect needle valves may vary in height or at least the point at which they operate and if not the packing (brass washers) certainly could. A manual on a later version of the PHH carbs suggested that the standard packer was 1mm and that a 0.5mm or 1.5mm packer lowers or raises the fuel level by about 2mm respectively. That sounds about right but I've never spent the time to experiment properly.
