Thinking back i remember my last 144 was 1972/L registration and had the later arrangement as you have uploaded. I'd previously had a 1971/K 145 with the breathers the opposite way round. When i got the L reg, i at first assumed someone had put the breathers on incorrectly and swapped them back to how i thought they should be and it wouldn't tickover properly - very similar symptoms to yours?

It seems you've tried most everything else, maybe the time now is to try the silly, stupid stuff and keep it that way?
Its a very late Nov'72 (L reg) with flush door handles... must have been one of the very last to be sold as the newer facelift '73 models were already being sold in '72. Hand written in the owners manual that it cost £2,374.98 (£32,047.26 in todays money)
