    Good morning, I own an Austin 12/4 New Ascot of Feb 1939, also of 1535cc. Although I am a member of the ATDC, I’m sure we have a like interest!! My problem is that, as I’m sure you are aware, this veh was manufactured with an ally head and cast block – result – disaster! Consequently over the years the old mechanics in their workshops have replaced the ally head with a cast one from a previous model. The problem there is the block water holes are oblong, and the cast head one is round.
    Would anyone in your organisation know if ‘a’ such replacement heads exist, and ‘b’ if they are prepared to sell!
    Thank you in anticipation.

  2. I HAVE A 1954 AUSTIN SOMERSET THE SUN ROOF IS STUCK IT WILL NOT CLOSE COMPLETELY HOW DO I REMOVE>>FIX>>AND REPLACE THANKS

  3. Peter says:

    Clive,

    You’ll probably get more response if you place your query in the Austin Somerset forum – see the ‘Forums’ page for details.
    Briefly though, it you check the front corners of the sliding roof you should find triangular plates, under the headlining. Each has a single screw-headed bolt which when undone will enable you to lift the front edge of the roof panel and withdraw it forwards, leaving the guiding bar at the rear of it behind. Problems with closing are usually related to inadequate lubrication of the runners or the track they sit in, or with the ‘snail-cam’ locking mechanism at the rear, which can flip over on itself if a bit worn. You’d need to carefully remove the headlining cover on the removed panel to see all of this.

  4. THANKS FOR THE REPLY PETER I AM A BIT WARY OF REMOVING THE ROOF LINING ( IS IT THE SUN ROOF LINING OR THE MAIN ROOF LINING ) HOWEVER IT HAS TO BE DONE SO I WILL GIVE IT A GO THANKS FOR YOUR HELP I WILL LET YOU KNOW HOW I GET ON CLIVE

  5. PeteJS says:

    Clive,

    It’s just the bit of lining that covers the sunroof panel – and really only the front corners of that. If you feel just behind each front corner you should be able to locate the triangular plates I referred to in my previous comment.

  6. THANKS PETE I WILL HAVE A GO AT IT WILL LET YOU KNOW HOW I DO

  7. THANKS FOR ADVICE NOW FIXED AND WORKING OK CLIVE

    I have problems in selecting reverse gear in my 1951 A40 Sport.
    Its a column change and it takes multiple goes to select reverse rather than 4th gear.
    Does anyone know of a tip to select the gear or is there an adjustment to solve the problem. I am aware of the need to pull out the knob on the end of the gear stick
    Regards

    I just bought a 1948 Austin A40 Devon. Can anyone tell me where is the chassis plate located? Is it the plate which is screwed on the glove box lid? or there is a chassis plate near the left side shock mount? I been told that for the early model austin A40 the chassis plate is on the glovebox lid and the later model the chassis plate mounted on front subframe/shock mount, so is it true? Please guide me. thanks

    Hey everyone!!

    I’m currently in the process of restoring a 1950 Austin A40 Countryman. As you may be aware this particular model has a wooden roof insert in it. My question is how were these roofs made as my original one has been to moved and over the years was lost by previous owners.
    Any help, drawings, diagrams, pictures or references would be very greatly appreciated.
    Thank you
    Matthew Austin

    Hi there have an Austin sommerset column change assume its three speed gearbox -could tell me how to locate Reverse gear on column change, Regards Alan from ashford kent.

  14. Rod Macdiarmid says:

    Hi folks
    As a young man in the early 1970s I had an Austin A40 Sports convertible for a year or so. BUT it was just a two seater. It had an aluminium body, with an egg crate grille. It looked very much like the four seat Jensen model, but was a little shorter. There was no evidence that it was anything other than original, but I can find no reference to any such car having ever been manufactured – anyone else ever heard of such a thing?

    how do I fit a core plug in my Austin Somerset

  16. Paul Thompson says:

    Hi John
    I have just replaced all mine when I rebuilt the engine.
    My engine is a 1500 Riley B Series Engine, the core plugs in this fit in a recess and are a dished washer.
    The principal of the core plug is that the core plug is slightly smaller than the recess in which it fits and when in place using a die you hammer the plug in to place which flattens it and as the dished core plug flattens it gets larger and thus tightening up in the recessed hole. you should use a sealant that sets firm. you can get brass ones that require less force to fit and as brass expands greater than cast iron are a better option.
    Please feel free to contact me by email if you require more info.

    Regards Paul Thompson

    I’m having trouble removing my 1950 Austin Devon boot handle. I bought the car in the UK 35 years ago and I’m just getting round to having the handle and hinges replated. I removed the four screws from the inside of the boot lid plate and tried twisitng it free but no luck. The handle works okay and it’s in the unlocked position. I’m going wrong somewhere. (I’m new to the website and I hope I’m doing this right) Tony Wright, no. 943, Lancaster, Calif.

  18. Tony Wright says:

    I do believe I’ve answered my own question with some help from the club. I found that the small square rod that goes into the locking mechanism from the handle was rusted into place and needed copious ammounts of penetrating oil to free it. (plus Gas in the UK I think) The handle should come out with a straighforward pull, but I had to prise it free with two screwdrivers used on opposite sides of the estutheon. Once on the bench, I punched out the small pin that holds the square rod in place and punched out the other pin that holds the lock mechanism. It came out with a simple pull of the key. Again, thanks to the club.

    My friend has an austin16/4 in india. The original carburettor that came with the vehicle was Zenith. Unfortunately, the float and needle is in bad shape and as a result he is now using a Solex and modified the air cleaner also. The performance is not the same. Could you suggest a remedy so that the original carburettor can be used again.

    Regards

  20. Bluescaster says:

    Hi Rallyman, You may have solved your (friends) problem by now but for what it is worth: The original Zenith carburetors do come up for sale occasionally on Ebay. or other internet sites. If that is not an option you may wish to repair the original carb. dependent upon what is wrong/how bad it is. The float valve is, I assume, the needle you speak of? These too are available – details of the needle valve are usually on them – if you have good eye sight;-0 take it out and examine it for the number. Also, unless very badly damaged, the float – brass in these carbs. can be repaired. First thing to do is drop it in a pan of boiling water – this will do two things. Firstly it will push out any fuel inside, besides pushing out the air and in so doing point to where the leaks are with a stream of bubbles. Remove from the pan and mark the position of the holes/split and then solder carefully (don’t use too much solder for fear of making the float too heavy.) You may need to go thro’ this procedure several times to make sure you’ve found all the leaks – although in my experience I’ve never found more than one pin prick or a seam split. Good Luck! Blue

    Hello all. I’m very new to the club (haven’t even got my welcome pack yet), but not to British cars. Have 4 MGAs, a couple of MGBs and a TR3 Recently acquired a 4 door Somerset that had bee sitting behind a dealer for a number of years. I did get it running but smokes worse then a teenager behind the barn! Now a friend gave me instructions to convert it to a MGB engine (original transmission). I was wondering if anyone has tried installing a TR3 engine? Seems easier, without the clearance problems in a LHD car? Also would MG (a, b or midget) suspension work on the front end? Thanks for any advice!

  23. PCT1959 says:

    Hi
    Although I did not convert it myself my Somerset has a 1959 Riley 1500 engine.
    I have removed and rebuilt the engine and most of the parts appeared to fit correctly.
    There is a slight difference in the bell housing and it looks like extra holes had to be drilled in the rear sandwich plate.
    Also the exhaust downpipe needs to be modified.
    Hope this is of some use
    Regards
    Paul Thompson Birmingham

  24. PCT1959 says:

    Hi
