Cobra (Thames Ditton) Forum / Original Smiths Gauges

Could it not be possible to redo just the faces?
I have heard of people who redo them for other brands, to keep the period look but with the reliability of a new unit.
Surely someone on here may be good enough with a computer to model the original Smiths faces and print a few?
Am I the only one who could not sleep with a "Made in UK" gauge instead of the original "Made in England"?

John,
Here are the jpgs of the drawings you did on the brake adjuster and brake bleeder.
Hello,
Any chance to see again the drawing for the brake bleeder?
It seems that the picture is no longer hosted on Photobucket.
Thanks.

Ace, Aceca & Greyhound Forum / Ace 2.6 radiator "upgrade" ?
« on: March 08, 2017, 09:17:06 »
Hello,
Thank you for the information. I heard of Wizard Cooling in the past but ignored they made a replacement radiator for the Greyhound.
As I am in mainland Europe though I am not interested in ordering from the US at the moment as we get murdered with import taxes.
Before anything it would be interesting to know the weight gain over the stock rad.

Mk IV, Superblower, CRS and other Continuation Cars Forum / Need a MK IV 16" front wheel !
« on: February 17, 2017, 10:09:14 »
On a more modern car I experienced a 200 mile trek home driving with the spare wheel on the rear axle. With quite a lot of power on tap and the opposing tyre being more than twice as wide, arguing with snowy roundabouts took a certain amount of commitment to avoid any disaster.
While this context was a bit extreme, I do not imagine anyone risking driving their MkIV in any spirited manner in the knowledge they have different sizes of tyres on the rear axle.
What type of LSD does the MkIV typically use? Not a Torsen I would hope?

Hello,
If the rear tyres on a MKIV are wider than the fronts and if both axles have the same width with the wheels removed, then CR may be higher than CF to give a resulting wider rear axle with wheels mounted.
DR is most likely lower than DF with the purpose of avoiding excessive tangential load on the rear wheel bearings while allowing for a wider (outer) rim, thus a wider tyre.

Interesting pictures, thanks.
Should the brake hoses be attached to the springs? Will have to check on mine where (if??) they are attached...

Austin Healeys (and no doubt some others) used this type of adjustable steering wheel (although with plastic rim and sprung spokes). it might be worth checking if any parts can be cross-referenced as the Healey wheels are remanufactured, e.g. AH Spares.
The nut available from AH Spares looks quite a bit different though, but it might be functional.

Ace, Aceca & Greyhound Forum / Carburettor synchronizer?
« on: January 15, 2017, 14:28:36 »
Pleased to say the Uni-Syn did its due. The airflow at tickover is so low that the adjuster on the synchronizer needs to be almost completely close otherwise the floater in the gauge won't take off.
Thanks again everyone for your helpful input.
By the way, which engine speed at tickover is everyone looking at with their Bristol engine?
Reason for asking is that mine reads "high" on the rev counter (about 1200 rpm), but the engine does not sound like it is running that high. I have not been able to read on a recommended idle speed in the owner's manual. I also wonder if the calibration of my rev counter could be slightly off.

Muffin, thank you very much for your help. I am not in the UK unfortunately otherwise I would have taken you up on your kind offer.
I just ordered a new Edelbrock Uni-Syn synchronizer. It seems to be a copy of the original MotoMeter Synchro-Test a friend uses and originally recommended to me. I did not feel comfortable ordering a used Crypton Synchro Check as the ones that occasionnaly pop up on ebay seem to have had a life, understandably. Looking forward to using it on the Solex and on the SU carbs of my other vintage British car.

Hello Muffin,
Yes, I duly took note that the spacer blocks could be drilled to receive proper vacuum ports fittings. However I feel a bit precious with the car and would feel better without drilling anything, unless it is absolutely needed.
What carbs did you have on your Mini?

Here is a picture of my center carb. I blew inside the port with a small pipe but as the picture suggests it is definitely plugged. All three carbs are the same. Just thought I would share.

Good feedback, thanks.
Solex most likely used a single mould of the throttle body housing and the hole may or may not have been drilled through the port as the housing made its way down the production/supply/logistic line, depending on engine application.
As decades of use saw carbs wearing out and ultimately needing overhauls that in some cases may have required replacing the throttle body housing for any reason, it could be that drilled housings were mixed up with non-drilled ones depending on what carb rebuilders had on the shelf at that moment.
Would be interesting to hear from other owners, to see if we have a trend.
Now to get back on topic, an open side port would be useful to measure vacuum when synchronizing the carbs.

I got confused and for some reason assumed that the Solex carbs on the Ace Bristol engine were 32 PBIC when they are in fact 32 PBI-6, which is actually just what's already mentioned in the AC owner manual (I know, RTFM and all that...).
The only difference I could spot between the two is the separate throttle body housing on the PBI-6 mating to the actual body of the carb with a 4 bolt pattern.
There does not seem to be picture on the Internet of PBI-6 carbs, but this illustration of the 32 BI shows a similar construction, and suggests that the vacuum port should be plugged with a screw plug labeled number 16.
Looking at the PBI-5 as used on some Jaguars, the vacuum port seems to be left open :
So what is on your engines, gentlemen?
Are your holes plugged or not? (pun unintended)

Thanks for the helpful replies so far.
Upon reading different period documents from Solex it would appear that 32 PBIC carbs feature a vacuum nipple hidden behind a screw plug on the throttle body housing, and that this vacuum nipple should be connected to some vacuum pipe on engines where ignition timing is vacuum-driven.
Could that plug screw be the one just below right of the plug for the main jet hex plug on the picture below? It seems way too small for hiding a nipple of some sort...
I do not have access to the car right now to check for myself.
