I need some help Identifying my car, motor, and carburetor

[hutchii]

Nick,
The "peg bolts" mentioned are flange headed bolts with an odd shaped spigot on the top, rectangular (approx 6mm width) with rounded ends. The rounded ends also taper from top to bottom. They attach the rocker shaft to the head. I'm sure like many things Citroen, a special spanner is available, but I managed to remove mine with an adjustable spanner set very tight and then tapped onto the spigot. As suggested in previous replys, I replaced with conventional H/T bolts during the rebuild.
You'll find many other "unusual" practices on these 2cv based cars. Wide use of M7 & M9 threads for example. 12mm A/F M8 nuts holding the carb on the manifold is another. So if you remove the carb, don't loose the nuts. An earlier post on this forum has pictures of modified spanners to enable easier removal of these nuts.

PS Be prepared to catch a significant amount of oil when (if) you remove the rocker covers!

Nick,
M8 bolts the right size can be found on ebay under item 301094800887.

Thank you all... your information is invaluable to me. What are the "peg" bolts you are referring to though?

Each of the rocker shafts in the head are fixed down with two bolts.... one of these bolts has an odd shaped head (peg bolt) that needs a special socket to remove. You can obtain this special socket from some Citroen dealers or you may be able to remove using a vice. The special socket is not cheap.

It is not always necessary to remove the rocker shaft assembly and you can usually work around it.

If the heads are going to be removed and replaced then I would strongly advise removing the rocker assembly. With the rockers and pushrods in place it is very very easy to crush the pushrod tubes and this would be something of a disaster over in the US where spares are few and far between.

I know that it is possible to juggle things around and avoid crushing the pushrod tubes but for the extra few minutes spent in removing and replacing the rocker assembly it is just not worth the risk. There are plenty of reports on this forum of even experienced people falling foul of this and having to perform emergency surgery using 11mm sockets and small hammers

Of course, the rocker shafts do need to be removed in order to carry out a proper top end job; a decoke, lapping the valves and fitting new stem seals.
Unless someone has managed to figure out a workaround which leaves the shafts in place...

Fwiw, a pair of good quality 6mm open-ended spanners used side by side will remove those peg bolts, especially if they're tackled whilst the heads are still mounted on the engine.
That's how I always used to do it before picking up one of the special sockets from a Citroen dealership which had decided not to work on A series cars any more.

Hi Nick

Just out of interest do you know the English registration number (Number plate)?

As Ken correctly says, you already have 99% of the parts you need. No need to panic. Get yourself a Haynes manual and work your way through it slowly. You will almost certainly need gaskets and so on, plus further advice with re-assembly. Compared to conventional (V8) engines, these are comparatively simple. Beaver away and come here for further advice.

So far the only number tags I have found were the Lomax one on the firewall I posted above.
