Apologies if posted elsewhere but saw this and thought - wow…that is stunning.

Something really weird going on with those spark plug leads, it appears to have an extra cylinder between pots 2 and 3.

 

Cylinders two, two and a half and three have twin plugs and one & four have single plugs.

4 cylinders 8 plug leads, its not too difficult to figure out...

Pretty certain I've seen the other one in existence that Skoda UK have on the A43 near Brackley.  If it wasn't that it was something very very similar in Orange with SKODA across the hump at the back

Not sure if you intended to patronise me or perhaps you have some previous with me.

 

I am quite au fait with twin coil wasted spark systems, twin magneto systems, twin point set ups to get longer dwell angle on 6 and 8 cylinder engines with single coils, I designed one of the first programmable (we call it mapping now) ignition systems.

 

If you read my posting again you will see that I am querying the positioning of the 8 spark plug leads, they are not in 4 pairs lining up with the cylinder pitch and the carb throats, it looks like the outer cylinders have one spark plug lead, the cylinders between them have two and so does what appears to be a mysterious 5th cylinder in the centre.

 

I'm sure your eyes are better than mine (if they are not then I really sympathise with you), perhaps you could look carefully and tell me what I have missed or misunderstood instead of being patronising.

Hi @J.R....   The image linked below should help.  They are widely spaced at the edges of the bore and slightly angled but definitely two per cylinder...

 

Thanks, that explains it perfectly

 

A copy of that drawing would make real man porn wall art!

 

I spent from the age of 18 through to 28 on drawing boards with drafting machines just like that in a string of jobs and contracts.

Same here - from 1986 when I was 18 I worked as a sponsored student at Dowty Group, moving between various machine shops / draughting teams and production control teams and then at 22 started as a highway engineer again spending a lot of time on draughting machines until CAD took hold in the mid 90's.  Somewhere I've still got some of the A0 drawings of the mining roof support I did in 1987 for the No 7 longwall face at the Bevercotes Colliery in Nottinghamshire - the GA for that was on my wall for quite a while at one stage!  I still do a fair bit of drawing and sketching to get info across (but mostly A3 sketching now) and have even worked through an 'Understanding Architecture Through Drawing' book to help improve my abilities.
