What carb?

[chesney]

I've yet to meet someone who maintains they do not have the skill or patience to operate a camera. It does not have to be a picture of the engine even, just a picture the OP has found on the internet that matches his setup.
Failing that, engine numbers and/or the description of filter location will have to be adequate.
externally, spin-on filters 'can' look the same to the untrained eye, and as I mentioned it is entirely possible for all A series to e fitted with a spin on filter. So providing a link with a photo of a spin-on filter may not help. Particularly when the link you have provided appears to go to a non-existent listing...
I have suggested there are two types of filter, but I've also suggested that it's possible for all A series to have spin-on filters.
Perhaps Autobahn's hands would be better used not following broken eBay links and providing indisputable proof, which saves all our time...

Unfortunately the spare carb I have is a H2 1 1/4" tag No: ACU852. Morris Minor 948cc 1957 -1958.

Well, yes. The 803 uses a spin-on filter down near the distributor. The 948/1098/MG1275 (of course) has a 'remote' filter housing and a canister paper element type filter down by the sump. The Marina 1300 has the oil filter fitted on the block by the heater valve.

It has the spin off oil filter.

The problem is the way the canister air filter secures means there is no way to adapt and fit to existing later SU as fitted

Work in progress, sometimes you start something and then wonder why?

[bmcecosse]

You are obviously well able to take a picture - how about you just humour us all by taking a picture of the engine - on the side with the dizzy. Our doubts are simply that someone has gone to the bother of fitting a larger carb and later type manifold - which would normally have been fitted to the later larger capacity engines. We're just trying to help you get the engine to the correct spec! The fitting you show on the earlier engine picture is not for a 'pancake' - it is the mounting for the later 'saucepan' paper element air filter, If you remove that mount - the face of the carb is not terribly different to an H1 carb - and you would quite easily I'm sure be able to adapt the early filter to that if you wish to do so.

It has the spin off oil filter

Yes, but which one?

Horizontal spin on/off = 803

Vertical 'up' spin on/off = 1275 Midget or converted 948/1098

Upside down spin on/off = 1275 Marina/Ital

Again a picture will give the answer!

[chesney]

Precisely!

Firstly I really appreciate the help from members on here, always a great place to obtain information from enthusiasts who have been there, done that and got the T shirt

I have not been to the car at my lockup since posting on here so photos show early days of restoration taken 9 months ago just to give an idea of what I am doing, however I will take some new photos tomorrow along with a photo of the oil filter.

Ok, photos of oil filter[frame][/frame][frame][/frame]

803 Series II A-Series - definitely!

At last! Much later dynamo fitted though - if going 'original' that would need changing.......

I think a better dynamo is not an issue, so that is staying.
But the proper canister filter is obviously so different and a nice original touch so will need to find a H1 carb.
Told you it was a 803cc

[bmcecosse]

Indeed you did - but you also need the early manifold to match an H1 carb....and of course you will lose some performance changing to the smaller carb... Frankly if all that worries you is the air cleaner - just modify it to fit the carb you have....

If you (or anyone) has been able to work out how this H2 carb can be modified to accept the earlier canister air filter please give me details.
I have tried to figure out a way to do it and don't think it's possible, but would be pleased to be proven wrong

[philthehill]

On the air cleaner down pipe -what is the distance apart from centre to centre of the bolt holes that attach the air cleaner down pipe to the original H1 carb. If my memory serves me right there are captive nuts inside the air cleaner down pipe.
Once that distance is known and if they are the same or similar to a H2/HS2 (60mm centre - centre) you may be able to work backwards to achieve fitment of your preferred air cleaner.
Everything is achievable with a little thought and imagination.

At worst - make a little adapter plate. I'm sure it's not rocket science.......

Everything is possible, but obviously consideration has to be the time and effort in working out how to resolve the problem and then actually make the adaptor.
As I said if anyone has actually done this conversion please let me have details.
No it's not 'rocket science', but not a simple fix either.

[bmcecosse]

It's highly unlikely that anyone would want to fit an airflow restricting early air cleaner on a later carb.... If I get a chance I'll look out the two carbs and compare the flanges....but there really is very little difference, from memory.

Is it possible it is the 'elbow' connection from H1 carb body to filter that if found could be worked to fit onto the H2 carb, I think this is the most likely solution.

Performance really is not an issue here by the way, I know I could probably cycle faster than this moggy

As previously mentioned my other 'toy' is a 600bhp Nissan GT-R, 0-60 under 3 seconds and over 200mph.

Both cars are black so hope I don't get them confused
