Hi All buggy has been going really well, starts first time, passed mot and been running good when I have used it locally, but had a flat spot when accelerating.  So and this could be a mistake had it converted to electronic ignition and had a vacuum advance distributor put on it.  Still starts and runs fab, ticks over fine but cutting out now when I slow down at junctions/roundabouts. Any ideas please what it could be?  The guy I normally go to is too busy at the moment to look at it so was wondering could it be something simple.  (I am hoping). 👍

what carburettor is it, may just need a speed tweek or a clean out of the idle jet.

Hi snoopy think it's a 34pict, could it possibly be that simple?  Because underload it does not miss a beat 👍

may just need a bypass screw tweak but ideally a full engine tune should be done first incase anything else has moved like  timing, valves or an air leak at a manifold joint.
