Re: How to adjust mixture

Hi Philip I found this photo of the screw in the same article that the previous photo came from. The article was posted by the TR group and describes strip down and overhaul of strombergs around similar vintage to our cars. https://s8.postimg.cc/hyos394vp/stromberg_needle.jpg It has a spring loaded ...

Re: Running Temperature etc

Hi Colin, Regarding those thermostats. One of our posters,Marekh, did an interesting research project some years ago where he discovered that most, if not all replacement thermostats available today did not open enough to close off the radiator bypass inlet, leading to hotter running. So you may fin...

Re: How to adjust mixture

Hi Hilton
I would start by ringing SNG.
A quick google search for stromberg mixture adjusting tool yielded several UK suppliers.

Re: Starter motor not disengaging

Hi Guys, I’ve got an early V12, fitted with what appears to be the same starter as in the posts, although I got mine from British starters.com in the US. The starter has been on for 10 years with no problems. It is a close fit but does not touch anywhere. I pulled the engine for a rebuild a year ago...

Re: UPDATE ON IMPORTED 2 PLUS 2 V12 1971

Hi Guys Ole, the relays I used are the 5 pin version with the extra 87 terminal, but we didn’t use it, so thanks for your input, others will benefit. I would be interested to see how you wired up the delay relay. Here is a pic of the 2 relays on top of the radiator. Yes, I have put in an alloy radia...

Re: Starter motor not disengaging

Hi Yes it’s easy enough to change the starter motor. Drop the splash guards under the starter motor, then it’s easy enough. Don’t bother to repair the old one. Just buy one of the modern geared type, Japanese manufacture, bearings instead of bushes, much better cranking, and half the weight. It will...

Hi Jerome, Congratulations on your rebuild, nice to hear you are going to drive it regularly. So for the fan upgrade Yes The fans fit in the same fitting as the originals with no modifications. I did spray can mine with black paint. For the relays I fitted two relays, one for the low speed side, rep...

Re: V12 Compression Test

Hi
Don’t panic if the hot idle oil pressure is 15-20psi, or even lower.
These engines are renowned for low oil pressure at idle.
It’s unlikely to be the oil pump, as they are also very reliable.
Cheers

Re: Jumping and spitting under acceleration

Hi guys When it comes to shining the timing light on the degree plate I found the best way was to get one of the timing lights with the adjustable tilt head, and a small screen to read the numbers from. It allows you to poke the head up between the hose and the degree plate whilst still being able t...

Re: Ignition Amplifier

Hi Andrew
You are probably one of the first to take the sng apart.
The AC delco chip was the one in the original HEI amp, and has been used in millions of cars in the US
I wonder if the SNG box has an upgrade over the original?

Re: Jumping and spitting under acceleration

Hi Andrew If you google search for AC delco D1906 you will find several sources. The amazon ad has a picture. As far as testing goes Perhaps the testing listed for the later cars with the CEI amp will be suitable. It is the same system. As you can see it is possible to open the amp from the bottom. ...

Re: Jumping and spitting under acceleration

Hi Guys +1 to Philips timing post.(apart from the porting discussion) Use 12deg Before TDC at idle with the vacuum disconnected, and plugged . You need a good timing light to achieve this. You will also probably have to clean up the marker plate and perhaps remark the degrees with a white marker pen...

Re: Jumping and spitting under acceleration

Hi Woolfi This topic has had lots of discussion on the board. I had my carb ported as per the original Jaguar idea which has the port on top of the carb entering the carb just ahead of the butterfly on the air cleaner side. This gives little or no vacuum at Idle, moderate vacuum at part throttle cru...

Re: Jumping and spitting under acceleration

Hi Hilton The Amp mounts in the valley where the original was. Don't worry about this as the internals of the amp are now a GM solid state chip, not the original style circuit board with its heat sensitive components. So the comments about moving the amp to the front of the engine for extra cooling ...

Re: Jumping and spitting under acceleration

Hi Guys Hilton to answer your questions Hot starting, is improved with the SNG kit, but the best technique I find is to try a start holding a little accelerator, if this doesn't work then push the accelerator to the floor and crank till she starts with a satisfying roar, generally about 2-3 seconds ...

Re: Jumping and spitting under acceleration

Hi The classic Opus failure mode normally doesn’t start until after the amplifier warms up. Your problem is with a cold engine so may indeed be carburettor related, have you looked at the colour of your plugs? On my V12 if I put the choke in too early when cold, the car will spit back through the ca...
