Well Flipping eck… looks like I should have gone to spec savers !! 

Looks like I might have got the old girl running on all 4 at last !

Before stripping the carbs yet again for another clean I decided to have a closer look at what was happening. 

The no 4 cylinder seemed to be doing very little when the plug lead was removed the lumpy tickover remained unchanged. However the header pipe was getting a bit warm although no where near as hot as the others. 

So in desperation I decided to slip the vac gauges on to see if that might show something and indeed it did !!!

The no 4 cylinder vacuum was well up on the others. 

I balanced the carbs and she started to run a lot sweeter. The header temperature evened out and she responded positively when the plug lead was removed. 

Took her for a short run and she is now running  just as sweet as  I remember back in the day  when I had black hair and a waistline.

it seems my attempt to align the butterfly’s by eye is no longer a reliable guide. I think the no 4 butterfly must have been virtually closed. I think the last clean must have cleared the blockage and my poor assembly skills tricked me into thinking that the problem was still there.

Like I said…” I should have gone to specsavers “

Thanks everyone for your input. 

What an incredibly valuable resource this is to have access to such a pool of experience.

Absolutely Fantastic !!!
