I'm trying to design this programmable ignition system so that it doesn't involve any permanent and visible mods. There are so few of the cars left worldwide that I feel they should be kept original as possible, but that's just me! I intend retaining the distributor so that in the event of electronic problems, reverting back is as simple as reconnecting the plug leads to the distributor cap. A number of people have fitted a "missing tooth" timing wheel to the MGB pulleys for use with the Ford EDIS controller, the Ford wasted spark coils and systems such as Megajolt, but I have some other ideas that I would like to try out. This will keep me busy while I am waiting to get the car to fix it to! I do have a test bed car I can use here, an old Nissan which has a BMC A series look alike engine. Now that sounds intriguing... I am on and off to fit a megajolt or such to my A+ engined Maestro. I run it on LPG most of the time, and the original timing is not really that suited to LPG. I would have bought a programmable 123ignition, as this requires next to no mods, but so far this is not available for A+ engines. Regards, Alexander

I had this with a regulator - swapped for another one and it was fine.

Good point... Something that mostly did not work for me here in Germany since the late 80s. Luck for me, is that I have a shop from one of Europe's major sellers of MG, Austin Healey and Mini stuff in my town Regards, Alexander

Aren't the Capri pads the same as Austin Maxi? I know that some Capri uses them. For the non-S Landcrab the brake pads from the late Austin Healey 3000 can be used and are surely easy to order through many specialists.

Many Hydragas cars have the fillers at the rear. The Princess might have them under the boot floor too - I just don't know. In the end they are easy enough to find when you follow the pipes or look at the rear displacers. The pressure needed will be much higher than for the landcrab. On older pumps the pressure gauge may not have enough range, it should work though. Lost gas will only affect the amount of fluid going into the car, the pressure alone determins the ride height (obviously influenced by the weight of the car.
If you want to do the car some good, evacuate to old fluid - it often looks like rusty sludge. But then you'll need to clean the pump afterwards...
If you start wtih an empty system, you can also roughly find the remaining gas pressure in the spheres: Write down the pressure read after every full stroke of the pump. Assuming each stroke displaces the same amount of fluid, the number of strokes counts the volume pumped into the suspension. As long as the fluid pressure is lower than the Nitrogen-pressure in one of the spheres, the pressure will increase quite quick. Once the fluid pressure is higher than the gas pressure, the gas cussion will compress and the pressure will increase noticeably slower when adding volume. So if you draw a curve with the noted strokes vs pressure, the curve will have one or two kinks - each kink represents the remaining pressure in one of the spheres. But there is no way to tell which one is the 'bad' one - usually the front will have less Nitrogen remaining.
Have fun!

Alexander

Ah, we have 3.5% CO as a limit for all car younger then 7/69.
Not that this poses a problem...

There is no compulsory emissions test for these cars in the UK?

Ah - found it. I have seen the sharp corner on a picture of the earliest 3litre known to me. It still has the Mk1 doors with the locking pin - and the rear door has a sharp corner on the rear top edge. The doors of our Mk2 1800s and my deLuxe 3litres do have the rounded corner (as do my Maxis...)

My father's simple rule was speed in kph divided by 10 = consumption in l/100km - based on many years of ownership. It is not too bad, just a tad bit pessimistic. The S is strong, but a bit of a drinker, even if I tried my best to get a modestly lean mixture with properly synchronised carbs. On the other hand I find it difficult to stay on the slow side of 80mph with the 1800 S - it always wants to take me beyond 85mph My Maxi 1750 is much more economical than the 1800 S - even when driven fast I never encountered more than 11l/100km. Usually it will be between 8 and 9 l/100km when traveling at speeds between 70 and 80mph. Regards, Alexander e

It looks like a very good figure. I rarely managed to get our 1800 S to use less than 10l/100km (or into the 30mpg area) - this only happened on a UK holiday with lots of A- and B-road driving and keeping to the speed limits. When the car was still young, the typical Autobahn consumption was about 13l/100km (21mpg). The 360km (225mls) drive to my grandparents was close to not being able to complete on a single tank of fuel. But the S always feels happy driven at 85-90mph.

Alexander

This must be a difference between Mk1 and Mk2 cars... My experience is with Mk2, 3litre de Luxe and later doors - and they are the same apart from the minor differences for mounting interior trim detailed above. Maxi never came with the Mk1 locks, 3litres with these locks are very (very, very, very) rare (I know of one).
Which point is rounced that is not on a 'crab?

Alexander

Ah, yes - the mounting strip for the door pockets. These are only fitted to cars with the short, deep pockets. I.e. Mk2 Austin and Morris models, also some early 3litres and late Mk1 Wolseley 18/85s. Maxis and Mk3 Austin/Morris models basically had the same door trims with pockets fixed to the trim. Mk3 and Wolseley 6 door trims will need the tabs at the top but not the strips to hold the door pockets...

There is a minor difference on the inside to hold the door trims. The Maxi has some tabs welded onto the tops to keep the trim in place. Mk3 Landcrab is the same. Otherwise Mk2 landcrab and Maxi are the same.
The rear arches are way too different: Maxis have an angle in the profile and a smaller diameter. Easier to shape your own bits if you do not need a full arch.
