Since finishing the rebuild of Millie my MGB has been running a bit rough more so on idle than any other time, also a bit of back firing happening,
I posted about this before and got suggestions of things to check, the majority of which I have done with no success. So I finally gave up blaming the HIF carburettors as being the fault after many happy hours trying to set them up right.
The issue seemed to be around number 3 and 4 cylinder which seemed to have no power and also had little impact on how the engine ran at idle when the plug leads were disconnected.
I ditched the HIF carburettors blaming them for the problem and I fitted the Weber 32/ 36, only to find out a day and a half later that the carburettors weren't the fault.
So let the fun begin, I've now figured it out, the story is in the video. Enjoy more than I did trying to find the problem..........

Thank you to all my subscribers and followers, comments are much appreciated, loving the encouragement to do more............. Hope you enjoy this one.
