Urgent question: engine conversion

[Minor-Bramsche]

Hi All,

I have an urgent question: the engine of my Minors is broken and I can get this engine for little money!
I need to hurry up to make a decision! And next - I need my Minor back on the road.

Please look at the pictures. Can someone please tell something to the enginenumber to me.

The engine should come from a Midget the seller told; is that correct?

Can I get the engine run smoothly and correct by using my HS2 carburettor?
Or do I need another carburetor? Which? Who has experience with such an engine?
Is there something on the pictures that does not look ok? There a little work on the engine I know.
My 123 Ignition should run with these engine I think.

It would be great if you can help me. sorry if the questions seem silly; I simply do not have enough experience at this time!

thank you
Dirk

The engine pictured will fit your Minor without any problems.
The missing parts can be sourced from your existing engine.
This engine was designed to run with a HS2 SU carb.

What engine do you have in the car at present? That is a 1098 'high' compression engine - missing it's backplate and flywheel unfortunately. It will run on your HS2 carb ok - but may need a needle change if your existing engine is not a 1098.

[Minor-Bramsche]

... at present also a 1098er engine is mounted.

[philthehill]

Changing your engine and swopping the parts over should be easy and pose no problems; the carb you have as it is already fitted to a 1098cc engine will be a straight swop as well with no needle changes.

And that engine is not from a Midget... but it's fine for your car. What's wrong with your own engine ?

[philthehill]

Whilst the engine may have been previously fitted into a MG Midget which is perfectly feasible the 10MA prefix on the engine number plate indicated that it is a 1098cc Morris 1000 engine block. The equivalent 1098cc MG engine has a 10CG engine number prefix.
You may occasionally come across a MG 1098cc engine which has a engine prefix of 10CC. That engine has the 2" main bearings and other small variations and was built primarily to be adapted for racing MGs as engines had to be built in sufficient numbers to be accepted by the FIA as a production engine.
To reiterate - the engine discussed in this thread is more than suitable for fitting into your car.

It has no provision for the mechanical fuel pump normally used in a Midget......

[philthehill]

Whilst there is no provision for a mechanical pump on the engine in question the Midget being spoken about may have fitted with an electric push pump as per the later Midgets or even used a puller pump as is fitted to the Minor.
We shall most likely never know the truth but the possibility should not be dismissed out of hand.

I suggest the seller will probably have mentioned 'Midget' in the hope of making it more desirable/valuable.....

Heh All,
thanks to all for your help but unfortunately I was 30 minutes to late sold to annother guy

What is wrong with my old lady and her engine; if I only knew !! oh it´s not easy to describe it in english. It is already not easy it to be described in German
A little less power the last months, getting very thirsty nearly 25 mls/gallon. Then she drinks oil like an old steamer a good filled pint per 220 mls ... 1500 miles ago, there were still 350 miles to drive before she ordered her new pint . at the last oil change after 3500 miles on the road the oil was thick as tar and It almost did not flow from the hot engine.
the compression is around 110 psi (8 bar) on all 4 cylinders when the engine is warm
But there are no bad sounds or other strange noises ... but a little bad feeling.
But my Lady is my daily and therefore it is hard to get her off the road for a lot of weeks. And I had never opened an engine before. Therefore I was looking for another 1098 cc to to do a overhaul and change the engine in a day.

What do you think about?
Thanks for your assistance.
Dirk

Oh dear - I would start with checking the valve gaps - 8bar is near enough 120 psi, not great - but it should still run reasonably. Your oil consumption is not 'desperate' - but not ideal either obviously. Are you using 20W50 oil? I don't see why the oil would thick as tar - unless it hadn't been changed in many a year. And of course - check and clear the breather pipes from the crankcase - and check if the air filter is now plastered with oil fumes and restricting the air flow. Take the element out and take it for a run - does it go better without the filter in place ?

[Minor-Bramsche]

The oil was 8 month inside and about 3.500 miles. three weeks ago I had changed the airfilter to K&N to test if it runs better with more air? But no difference. Changed back to original. the original was not filled with anything absolutly clean.
