I'll wait on!

Thanks that'd be helpful! If Sam can't get ahold of the CAD drawing I'll let you know. The thing I really need is the relationship of the block mounting bolts to the centreline of the crank, which should be the same between any 6-cyl car (and only one bolt different for the 4-cyl ones).

But not sparklers on wine bottles: https://www.bbc.co.uk/news/live/c8xdxvj2qjdt  

BiTurbo, I looked in the workshop store (Back end of garage) and I have a 2L backplate that I think is from a GT6 or Vitesse.   You would be welcome to it, if you would pay for the postage, which would be about £6.  Certainly less than daughters to the white slave trade. Bests John

Now I've just got to try that 🫣

I ssem to remember having to shim the sensor closer to the trigger wheel when I did the Sprite. 

It's been a while since I moved away from the megajolt, but I'm inclined to agree with Nicks approach.  Set the system up so it is capable of generating spark and check this before getting too worried. Other suggestions are:  check sensor to trigger wheel gap to give best chance of generating a strong signal.  Then check that the sensor wire is kept away from the coilpack and plug leads, and that the shielding is connected up nicely.  This will give you the best chance of the signal having minimal interference noise. Other musings are that I managed to get my electronic rev counter (smiths mk4 spitfire) to work directly, however it took a few seconds and often a blip to over 2.5k rpm for it to start working.  It still does that with the new ECU setup so I think this is probably an issue with the rev counter or other wiring rather than the ignition system signal.

I had numerous discussions with contractors who were slinging together wood pellet stores.  Yes foreman, I'm afraid the earthing and explosion relief details do need to be constructed as shown... They must have missed the custard powder experiment at school.

John there used to be a great resource of “how to” on the tr web site  but it’s not there on the new system i will pm you the email for larry the champs coordinator   

Thank you, Hamish!   I missed this previously. I'd like to do some of these for 2026, especially as some (Aintree, 3 Sisters) are almost local to me.    Should I register for the series?  Where, please? TRR? John
