Problem inserting in 'for sale'

Hi,Twice yesterday I tried to insert an advert in the for sale. Titled Jodie is for Sale. It doesn't seem to have been received on either occasion. At least it has not appeared and I have received no other acknowledgment. Am I doing something wrong?? I did try to include a jpg picture with it using ...

LCT 899, UKB125, 48 YMA

Anyone know anything of the above, They were our family cars between 1957 and 1973. (we had several others but the reg's elude me)
DVLA searches reveal nothing but perhaps someone remembers them.
Thanks

Re: funny noise

Isn't the clue in "stops when I apply the brakes"? I have known the pull-off springs to rub on the hubs, or the shoes to move into contact with the brake drum. both cause odd noises which cease when the brakes are put on. Does the noise also cease when the hand brake is applied lightly whi...

Re: Engine timing (again)

I always set the ignition timing by disconnecting the advance vacuum, then gradually rotating the dizzy from TDC at tickover to a point where the engine revs cease rising and the engine sounds a little less than happy.Then retard it just a bit (a smidgen). The engine then sounds happier again. Lock ...

Re: PCV valve

The other aspect which may need attention is in the control of air into the engine. I couldn't get tickover below 1200rpm when I first had the car (I was told this was due to the mildly hot road cam fitted). After much work looking for an air leak into the manifol, including a fitting of the Fish ca...

Re: PCV valve

East Sussex Minors sell the valve for £24, part number FUL 144, or so they tell me. Also the diaphragm is available (not sure where I saw it though; it's one of the interweb sellers)

Re: Heater bypass when using mini heated manifold

We do seem to have wandered from heated manifolds to manifolds in general! Still its all related. I have been on the internet reading some of Vizards tests on the airflow through manifolds; that is interesting. Must buy the book.

Re: Heater bypass when using mini heated manifold

It would be interesting to see, it works for motorbikes. I believe SUs don't like working to one cylinder as they don't like the pulsating flow.

Re: Knocking when warm

Big ends are a lot more of a rattle than mains and you can "play" them by varying the engine load at fairly constant revs. The latter is/are a deep distressing thump and are worse a low revs. and the rear can be felt in the clutch when bad. Small ends are a lighter tap and are worse at lig...

Re: Heater bypass when using mini heated manifold

1342 is only "proper" when you start at 1! I have seen manifolds with a division so that the mixture should split to serve either 1-2 or 3-4. 1432, as ford do it can also be re-written as 3241 which is not much better than BMCs layout. I guess 4 carbs and very straight short manifolds as m...

Re: Heater bypass when using mini heated manifold

I wonder sometimes what the air/fuel mixture in a manifold moves like: it must be pretty violent in there! First inlet valve 1 opens: mixture rushes forward to that cylinder, then stops and reflects as the valve closes. Next up is No 3, the mixture flow reverses, violently I would guess, to fill tha...

Re: Heater bypass when using mini heated manifold

First, off e-bay, look for "Reece Fish" or "Minnow" or "Fish" in car spares. Most of them are for VWs and are configured as downdraught but the side chamber is rotatable to give side draught and they are largely self adjusting fuel wise. They work by using a hollow butt...

Re: Heater bypass when using mini heated manifold

In the 60's I fitted a Minnow Carb to my Traveller. It transformed it! More power, almost instant performance from start-up (no choke) and better fuel consumption. All together. It was said that it was all due to improved atomisation and no restrictions being required to to give a venturi effect: th...

Re: more woodwork q's

I used Sadolin Antique pine Advanced one coat woodstain. It seems to be the correct colour and worked on an area that had previously been varnished in the rain and had gone an awful grey colour. I sanded this off first of course.

Re: Heater bypass when using mini heated manifold

That doesn't fully explain why nearly every manifold was heated. One explanation I saw was that the walls of the manifold are cooled by the petrol in the incoming charge evaporating. This caused petrol to condense on the walls of the manifold which then resulted in an overweak mixture when the throt...

Re: Heater bypass when using mini heated manifold

If one is over 60 it's free, but the car is still more useful in most operations (Tesco for example). Back to the subject: I suppose that the optimum temperature for the manifold is just below the vapourisation temperature of petrol. This is quite low, 70F comes to mind. So perhaps the manifold heat...

Re: Heater bypass when using mini heated manifold

Certainly the volumetric efficiency, everything else being equal, is improved if the air is cooler as the weight of air going in is increased. Presumably the manifold is heated to aid vapourisation and hence improve the balance between the cylinders. The designers must have known what they were doin...

Re: Heater bypass when using mini heated manifold

No, it has four pipes, two go backward to connect to the heater. The Solenoid valve closes the topmost flow pipe which cuts off the heater but also opens a transfer port which returns the hot water directly back to the head. All fiendishly clever!!

Heater bypass when using mini heated manifold

I have just fitted a useful bypass valve so that I can turn the hot water to the heater off whilst maintaining a flow through the Water heated mini inlet manifold which my car Jodie is fitted with. It uses the solenoid operated valve from a Ford Ka. There are any number of these available new on e-b...

Re: Electric supercar

Does anyone remember the gentleman from Somerset who made a steam car using two cylinders of an A series engine in a Morris 1000. Supposed to be very economical and almost silent.
