Please keep us posted with this - I have a similar problem, but it appears (in my case) that the accelerator pumps when activated are simply pumping too much fuel into the carbs; this of course can be adjusted if this is actually the problem but is it? Could be high fuel pressure, poor float valves or ..... I don't know yet.  :confused: 
I am on a learning curve and "information seeking" venture with the issue.

“Electric fuel pump with a regulator”

High fuel pressures cause the fuel to “squirt” and create turbulence in the float bowl.  This messes with the jetting.  Fit a proper low-pressure fuel pump that does not require a regulator.


Hi John - I've just read this thread and stopped at your above comment. Do you have a recommended fuel pressure for Dellorto 45's - my new fuel pump is running at 3psi without a regulator in line. Would you consider this too high?

Garage / Re: How Does a Voltage Stabilizer Work?
« Last post by BDA on Today at 09:27:29 AM »
MGs and Lotus (Jaguar too?) both use Smiths gauges (I believe Jaeger and Smiths merged at some point). Besides gauges, Lotus utilized several parts from MG (inside door handles), Jaguar (TC outside door handles and tail lights), and Triumph (steering rack, front uprights, front hubs) and surely many other smaller parts.

As for the orientation of the gauge making a difference, I would guess that the weight of the needle and associated attachment could be the cause. Catching up on how Lotus gauges work (which is to say how Lotus Smiths gauges work) might help you understand (http://lotus-europa.com/manuals/misc/electrical/meterinfo.html).

You are purchasing a Smiths Gauge Voltage Stabiliser For MGB, Triumph TR4 & Spitfire MK1-3

 Regulated 10 volt supply - Positive Earth ONLY

If you do a search for the part number Dilkris posted, it is indeed a negative earth unit.  The NEG in the part number should be an easy tell.  From what I recall, the difference between various part numbers was the obvious positive/negative ground, and mounting tab location.  For the electo-mech units, you do have to keep them in the correct orientation, hence the arrow or the word TOP, the newer solid state units should be able to be mounted in any orientation.  Also, some units are still electro-mech, not all are solid state.

I'm lost - where do MGB's, Triumph TR4's and Spitfires come into the equation.   :confused:
What have I missed?

The only thing I wouldn't use is air although I suppose if the calipers weren't split the piston can only fly as far as the other side of the caliper body.

I second that - I only used air once on stuck Triumph T160 front disc caliper pistons  - they came out but it was bl**dy dangerous and never again.  :(

Garage / Re: What are we missing, what should I make on a VMC?
« Last post by Richard48Y on Today at 08:53:53 AM »
I have not seen any for Webers on the Cross-Flow Renault.
In theory I can make almost anything the VMC would have done on my manual machine, just much more slowly.
The VMC is still a possibility if I can raise funds again.

This is interesting - I have just been along this journey. Couple of days back I posted "Dilkris Update - Back at it!" (but I put it in 'Technical Articles' which was probably wrong) - anyway it was about me starting the engine finally after some time away from the project. 
I wired up a temporary temp gauge circuit,(without the voltage regulator), and upon the engine running it was showing 130 degrees - I then realized that this 'magic cube' was not an option as it does, amongst other things it seems, reduce voltage to the temperature and fuel gauges to 10V.
I have now installed it, (original item - see pics), and temperature now stabilizes at just over 90 degrees.
If you need any more readings please let me know as it is presently very accessible. 
Also in researching this component on line - (it was made by Smiths Motor Accessories BR1311/00) - it seems that how it is mounted is important to it's operation - ie: it appears it can only be mounted one way - please don't ask me why - I followed the instruction and it works...  :confused:
Please refer photo of BR1307-00NEG which I assume super cedes the original - read description
