Hello David, Noted about the timing, Won't get much car time in the next week or so but I now have all the equipment to get it done so watch this space.
I am not aware of any internal engine modifications. The previous owner kept a list of the things he knew about and passed that on to me but he also said that the owner before him did not keep records of any changes made. I am surprised that the one obvious modification was not made, namely to go to the twin carb S spec.
Is there any way for checking for air leaks in the vacuum pipe, would this affect the rpm?

Had a good old tinker over the weekend. I was inclined to retard the timing a bit but couldn't shift the distributor, maybe a good thing as I am sure the previous owner knew exactly what he was doing and set it up properly. I had a play with the carb. It was dying away under the lifting pin test so I have richened the mixture a bit. The mixture control cam was not clear of the fast idle screw so I corrected that. Finally I tightened everything up between the carb and the engine and all together this has dropped the rpm to about an indicated 1000 and stopped the running on. The car went just as well as ever on a road test including motorway speeds. I tried to make it pink but there was nothing.
I know it's not perfect but think I'll leave as is for a bit to see where it settles.

These wheels and tyres are currently on EBay. I don't want them myself but what has arisen my interest is the list of suitable vehicles for these wheels. Austin 1800, Vauxhall Cresta & Viscount, Humber Super Snipe, Imperial and Hawk, Rover P5 and P6 and oddly the Ford P100 (Cortina V pick-up) Do all of these have mutually compatible wheels? On a different but related matter I notice that the choice of available tyres for 14" wheels is much wider if you go for 175/80 rather than 165/80. Has anyone changed their rubber recently and what did you go for? Nick

The tacho fitted is a modern Durite item, you can probably guess what is coming...
I had been thinking that whenever I looked it when driving it only ever seemed to read about half what I was expecting. The Durite catalogue lists it as suitable for 4,6 or 8 cylinder engines and yes, I have now discovered the little switch on the back of the instrument. I'm not really covering myself with glory this week am I?
Idle speed when the engine is warmed up is 1300 to 1400rpm. I will do the other tests over the weekend.

Digital Tachometer ordered and on its way. I'll report back with some proper stats after the weekend. Nick

Good call Chris, The line on the pulley is painted though like the marks on the pointers has yellowed over time. I'll redo them when I get round to recording the advance at various rpm. This slightly blurred pic shows that the marks really won't be visible from the other side of the pulley so I can't replicate the diagram in the manuals. BTW I got to grips with Flickr. Only part of the URL code is required to upload the photos; good old Google. Nick

Hello David, Thanks for putting me right, seems obvious now but I was really scratching my head last night. I can't see the pointers from the other side of the pulley so will have to carry on from the wrong side so as to speak. There five pointers, will these cover 20 degrees of advance? I need to sort out a tachometer of some sort as the one fitted to the car is hopelessly inadequate and never reads much over 2000rpm whatever speed the car is doing. I'll report back on the readings when I get one but just from listening by ear I think my idle speed when the engine is warm is over 1000 but probably a lot less than 1500.
As for your other points. The engine doesn't take too much cranking from cold and almost none at all when warm. It pulls strongly from just about any speed and there are no flat spots. The fastest I have driven or want to go is 70mph. I heard pinging under load when I accidently put some 95 unleaded in but 50 miles later I filled up with 97 and added the last of my tetraboost lead additive and am currently on equivalent 99 octane and the the car runs fine with no pinging. This is making me wonder if the ignition has been advanced a little to get the most out of this fuel - the previous owner said the car was much happier using 97 + additive. Nick

Bought myself a timing lamp and hooked it up this evening. The picture shows what I think are quite ragged looking timing marks or at least not at all like those in the manuals. Just to give you the geography the green paint is the bottom of the radiator housing. At idle the mark was close to the pointer at the back (on the left) which I am guessing is 0 degrees. Trying to align to this with the dial gave me about 3BTDC and increasing the revs saw the timing marks move clockwise way from the timing marks. I wasn't expecting this and as you can probably tell I don't really know what I am doing. Nick

Thank you David, I checked it today and the green LED comes on around 12 degrees which isn't what i was expecting from reading the 123 instruction sheet. I won't mess with it any further until I get myself a strobe timer. Nick

David, Thanks for the advice and links. I had already downloaded the manual for the generic British 4 cylinder version though I am not 100% sure which one I have. The original car spec says 12BTDC @ 600rpm. Is this what I am looking for or should i be referring to whatever curve the 123 may have been set up on? Forgive my ignorance, I really am starting from scratch with this. I don't even own a timing lamp (another trip to Machine Mart calls)
The idle seems to be pretty steady once the engine is warmed up, if anything it gets a little faster but not much.

Good points well made which will form the checklist for this weekend hopefully. Kels, I am generally overcoming the running on by making sure that I switch off the ignition just after parking up with the car out of gear, yet before the revs rise too much, it seems to do the trick. I hope that when I manage to sort out the fast idling that it more or less cures it. I hasten to add that I would never stall the engine to stop it - too much stress (on me and the car) I'm hoping it is not the ignition as I am rather regarding the 123 setup that I have as a sealed unit at the moment. I check the other bits first. Nick PS another attempt at yesterday's picture loading now follows hey-hey !

www.flickr.com/photos/95554091@N03/8717714317/Have just signed up to Flickr to see if uploading photos to here works better than the proboards system. Chris, I know you have posted how to upload photos from sites like Flickr somewhere on here but i can't find it. Any chance of a re-cap? These last few weeks I have been using the car a lot and it seems to thrive on it. I am also working my way through the annual service items bit by bit. Coolant change and radiator flush at the weekend along with the valve clearances. Spark plugs came out looking good apart from a little soot on No2. It's idling too fast though and I've backed off the idle screw as far as I can. Reading the web it looks as though vacuum or an air leak could be responsible - any ideas? It also has a tendency to run-on. It made me late leaving the garden centre the other day but it was nice late; people came up wanting to look at car and talk about it. Probably happens to all of us but good all the same. Nick

I haven't given much of an update recently. Life with the Wosleley has been fairly uneventful but in a good way. The current drain has not reappeared and the car springs to life much better these days thanks to a new Bosch 096 battery which ought to be up to the task of operating all the gizmos I have.
I went on my first journey of any distance to the Pride of Longbridge event on 13th April and met up with some friends. They all own modern MGF/TFs and had the misfortune to be allocated a slot near the Rover 25 owner who's stereo had a bigger engine than his car - unlucky to say the least. I think I was the first Landcrab there but another Wolseley appeared just as I was setting up to park so I had company. That was the theme for the day really. I have worked motorshows many times before and made sure that I engaged with people who looked at my car and had a great time to swapping stories about both the cars and the factory. I just had to remember I wasn't selling. I didn't get time to take photos but there are loads of the event on Flickr if you want to look. I think in the end there were about ten crabs and one lobster present, not all parked together though. I also got to meet some members of LOCI who were very welcoming; one of them bought a Six that I had looked at last year during my buying phase. By 2.00pm it was raining and most folks were leaving. There weren't many older cars on the M42 motorway and I settled down to a 60mph trip home. I almost wish my tyres were worn so that I could replace them with the correct size and drop the rpm.
The car is idling too fast so that is the next little job, I think I need to check vacuum connections and tappets if the literature is correct.
Last weekend I used the car again for all the local chores, like going to B&Q in Coventry. It's great to use the car as a normal day to day vehicle and it always surprises people who see it. However I didn't even manage the four feet that Chris did on Drive it Day; took the children for a bike ride instead.
