How To: Restore a Morris or keep fit

This will likely mess up the idle circuit. You might need to fit a fuel pressure regulator? I would put a gauge on it first.

Just to add to what Lynn has written

Some of the older Solex carbies are extremely sensitive to fuel inlet pressure- this I think stems from the days when many cars had the petrol tank mounted in the cowl and the fuel gravity fed down. I found this out after I spent a long time fiddling about with a Series 1 Land Rover Solex carby . In the end the problem ( running rich ) was not in the carby , but in the SU electric fuel pump . The pump spec was 1 to 1.5 psi but it was actually around 3 psi and this oversight caused me much grief along with frustration.

Mike,
There were two types of SU pump, high pressure and low pressure. For example a Morris Minor had the pump on the bulkhead and was a low pressure, whereas the Mini had the pump at the back near the tank and was a high pressure as it had to push the fuel further. I guess the delivery pressure at the carb equalled out between the two types. If using a SU pump it pays to check what application it was designed for.

Mike I am sorry my problem has taken over your thread, but the news is good as yourself, Lynn and Richard have given me the answer to my problem. My C8 has the regulation carbi Solex 35/40 FVS and pressure has been my problem, I reinstalled the manual fuel pump, isolated the 12v pumps which are lifters close to the fuel source so work on about 4 psi and fired up the engine. The fuel/air mix screw was effective and I adjusted the idle, job done. I removed the manual fuel pump after to give it a service prior to final installation, I will go for a run tomorrow just to be sure all is good. I have left the 12v fuel pumps and the in line filters installed as I may use them for priming later down the line and don't seem to worry the system, I have the same 12v pumps on my Austin Champ so the later Solex carbi must be ok with the extra pressure. Many thanks to you all for the sound advise. Look forward to more pictures of your restoration Mike as it progresses.

Good news. But don't break the speed limit in your C8 during the test drive

Us MCC owners have to stick together, we are few and far between in this far flung outpost

The old leather pinion seal on the CS8 rear axle is worn out and the 2" yoke had a deep groove worn in it . I decided to machine the yoke down to 50mm . I can buy a new 50mm pinion seal with a 70mm OD, this is close enough in size to the 2 3/4" original OD of the old seal .

I also had a win on EPAY and scored 4 new tie rod ends and some new front spring bolts and bushes for a cheap price, these are DUFOR brand made in NSW .The CS8 surprisingly has rather small diameter sized front spring pins, same dimensions as the Morris J2 van actually . The tie rod ends also fit a "Hillman Wizard" whatever that is ! and other vehicles from mid 1930's to early 50's including a MG .

Hi Mike and I am sure to hit 30mph tomorrow even though there are no hills near home in Point Vernon, you did well on the net gathering stores and even stuff from the early 30's from the wizard and as for the J2 well not the most pleasing looking thing that grew 4 wheels. By the looks of it you are like me and tend to machine things to what you need, I have a neighbour who lets me use his mini machine shop when needed but I had to pass his test a few years ago, he inspected some bushes I made which came up to his standard so I passed. Long time since I worked on machines but like riding a bike.
Will keep an eye on the leather seals as I have a nuisance leak on one of my back wheels, I am also wondering if my C8 is on the Aussie Army list that you are formulating? Chassis # 2283C8GS033 as I am hopeless on this kind of thing, I have my champ Aussie Army record someone sent me a few years ago as he had access to the ledger. Lots of luck with the C8 resto and again many thanks for the help.

It's actually a CS8 I am restoring the "S" indicates a six cyl. engine . It is a 4X2 .

Hi Paul,
Glad to hear the fuel problem is hopefully sorted out now.
Regarding a rear hub seal, I think you will find that it is a felt ring. I found some of these some years ago for a C8 and they were still available from British Leyland in the 1970's-80's under the Unipart in-house spares label. I think they were used on the LD and some of the FG models from Austin and Morris.

regards, Richard

The CS8 has a felt ring behind the inner hub bearing , its a pretty crude seal but it must have been effective to some degree. The felt sits in a steel circular holder that RESTS AGAINST the bearing. You can see the felt ring behind the bearing, in the pic I attached with the can of WD40 .
