German Fiat 126 Bambino engine.

Probably a question for one of our continental bros but does anyone know if the German Bambino engines were designed to run on unleaded petrol ?

Personally (That means could be wrong) 

The square heads were on the early 126s. (up to late 80s, very early 90,s) so I would be suprised if they were.

now i think we should not refer to anything german as squareheaded this is very anti...

It's fine as long as we also talk of Roundheads to keep it balanced. eg. That Cromwell used to take things a bit seriously didn't he.

Now then , now then ! 
Well the thing is that the Bambino head apart from being square has a number of other differences. The spark plugs fit into a deep steel liner and the head mounting stud holes also have a steel liner . So a robust build with a bit more bulk that will help to disipate heat like the Panda 30 head .

Thought I would bump this one up just in case some one knows the answer

On a Dutch forum I read that every 126, since engine code 126 A1.076/E, may run unleaded. I also checked the German forum and after reading some posts I believe no one there runs on leaded, square or not, old or young.

All the engine of the 126 can be used with unleaded fuel.

In the Polish sources - the heads since 1990 - appropriated for unleaded gasoline.

PS - all of the 126 are good for unleaded... Do you thing it's the main problem!?!?!?!?

Thanks for the input guys 
It is just that I have this Bambino cylinder head which was mis-sold to me as a Panda 30 head a couple of years back. There are issues/problems with fitting this head but I think I have come up with ideas about how it can be made to be interchangeable with a regular head. The head came with a large twin choke side draft Solex (like a Weber 40 dcoe) carb & manifold that some idiot had tried to bodge fit it. I am still thinking of reviving this project and if the head is OK for unleaded fuel then that gives me more incentive

The old twin choke, side draught solex is a really good, nice sounding carb. I recommend relocating the airfilter to the back of the shed, sounds lovely there.
