Arrghhhh what's happened ?

I Can't sleep now the engine is not good : (

Initial problem we had was getting the carbs balanced and getting a good base setting what ever we did the carbs were flooding; wouldn't idle andc no matter what we couldn't achieve good base setting, very strong fuel smell and plugs wet no. 3 and 4 nearside bank of carbs (twin weber ict's 34)

Carb float settings checked 6mm 12mm then found a chunk of swarf in float chamber ? Removed this carbs now running no overrun or flooding. Checked fuel into carbs ok now but still a question over fuel to no. 3 but makes little sense as fuel getting to no. 4 and the plugs look rich (were wet at one point)

Next and BIG problem:
As couldn't get engine to run smooth but having checked the carbs and fuel we then Removed no. 3 lead and there is no change in engine speed so no. 3 is not firing ?

Checked firing order was ok on dizzy and leads fitted correctly tried new spark plugs and checked with known good dizzy cap and leads still no fire on 3!!!!

Thought this could be overtight valve on number 3?

Quick check of engine timing its set at 2 degrees before tdc by TES and clearly wants to stall (shouldn't this be set at least 7 degrees advance?)

Checked the point gap this is very tight almost no gap
Point gap should be 16 / thousandsth ??

This would result in weak spark missed or weak ignition / spark?? I.e. not firing in number 3

checked valve clearance very tight on intake and exhaust 4 and 3 these were very tight almost no gap on 3 and 4 intake but also exhaust. Adjusted to recommended gap as per running in instructions 8 / thousandths

We have read for compression around 120 and within about 5 for each so shows ok compression ? possibly need to recheck compression on number 3 carefully!

WHAT HAVE WE MISSED ?
