Not wishing to intrude on the former thread, my RP has developed a slight problem where it oils/cokes up the plug on n°3 cylinder. In an attempt to reduce the problem I have changed over from B6HS plugs to a set of hotter running BP5HS. The car is a standard RP saloon with a 37 head and H1 1 1/8" SU carb.

On Sunday 4th we took the car out for the annual winter rally and I had to stop twice to change the plug on n°3 because the car started misfiring. The car also seemed to be a bit down on power, but I put that down to the fact that I had a slightly over average sized co-pilot... 

I have since done a compression test, thinking that it was a bore wear problem - the engine has been +.030 oversize since time mint imperial and had a new set of rings, valves & valve guides circa 2005, possibly a bit earlier.

The results of the compression test are as follows: (cylinders 1, 2, 3 & 4)

Cold:  (psi)  100, 100, 110, 95  (I put the slightly higher reading on n°3 down to the presence of oil in the bore).

Hot:   (psi)   130, 125, 125, 130

So I guess there's not much wrong there.

I will be removing the engine/gearbox when the weather gets a bit warmer because the clutch release bearing needs replacing, at which time I will strip the valves out, regrind and check the seats & valve guides. I suspect that oil is being drawn up the valve stem on n°3 cylinder - when I did the "Col de la Bonnette" some years back there was a valve sticking afterwards but I can't remember which.

Oh yes, one other thing. As I was stripping down the engine prior to the compression test it looked like the piston ion the carb was stuck in the down position, but I can't be sure if that was just down to me working on the engine or whether it had been like that during the run. Mind you plugs 1,2 and 4 were all the right colour. Just n°3 was acting up.

Apparently we're in "La Vie de l'Auto" again too...

Any other ideas?

Val Brookes - who helps maintain the Stadium information and patterns for the GE Register - has contacted the company (with the help of Damian G-T) who made the last batch of enamel badges.

They will make more for the price shown below.

If you are interested contact Val in the first instance through this post and she will coordinate with them, production is due to complete for October 2018.

With my special still in the planning stage, I have a blank sheet of paper and would appreciate your advice.

The Austin Seven in common with the Austin Healey Sprite share quater elliptic rear springs and inherent roll oversteer. This I believe is a result of one spring lengthening and the other shortening as the car rolls through a corner. I think this could be eliminated by either an A frame Rose jointed off the chassis cross member close to the torque tube mounting or parallel radius arms. 

I'm sure this problem has been tackled although I cannot find any information.

Thank you

Is my memory playing tricks with me? I've been looking for a factory photo I remember clearly of almost-complete Mk2 Rubies on the production line. I thought it was on the A7CA website but there are no historic photos there. Nor are there any technical drawings (chassis, coachbuilder's setting out plans etc.) which I thought were on the same site.

Anyone point me in the right direction?

Peter.

I have a block 
M 268616 which has had to replace the cracked 88xxx original

Should  I use either new plain guides or shouldered guides?
Or does it not matter?

Hi folks,

There seems to be a million types of LED
bulbs available , but finding a LED headlamp bulb that is 6v, 
Fits a BA15 socket, is negative earth and offers
Full and dip beams seems be the one type that just
now anyway is not available?

Or has anyone else located a source of these?
Ideally one that does not look like a “ pineapple” !

For fitting into new old stock 1925 CAV headlamps
which have clear glass lenses which reveal all.

I am looking for a 29/30 type RK Saloon body - anything considered.

Many thanks

I  am buying a new trailer so I need to sell the old one. It's nothing flash, I think it was originally used for a mower or similar. There is a pair of ramps and a chock fitted at the forward end to set the balance point for easy handling off the tow vehicle.
Recent new tyre, new jockey wheel, new adjustable rear legs for loading.
It is braked but the brakes need some TLC.
The pic was taken on the way back from le Puy-Notre-Dame 2016. I can take more pics if wanted.
£250.00 ono.

I hope this one finds a good home.

I decided to take the carburettor off the AG to clean it out ( the AG has a "sports" head. & manifolds) and a downdraft Zenith 30VE1 carburettor no 3935.
With the carb off I could see into the inlet manifold and there was a good quantity of what I think are cherry stones in there! I have had plenum chambers filled full of nuts placed there by squirrels in the past, but this is a new one!
I decided Hoovering them out might not be enough, so set about removing the manifold. The four vertical bolts came out and the  nuts on the exhaust manifold (I undid all, but I think only the middle ones are relevant. The inlet manifold is now loose, but will only pull away from the head about 1/4". No amount of jiggling nor light tapping wit a soft hammer will shift it.
What else has to come off? Please not the exhaust manifold & flange joint!
Or do I hit it harder!
