This one has me stumped. I've got a K reg sprite, standard, 1275 on a HIF38 carb and electronic dizzy.
While driving at a steady speed there will be a sudden complete loss of power, and the engine is unresponsive to the throttle. After rolling along for 10-15 seconds or so trying to find somewhere to pull over it'll come back to life and drive again, only to repeat the process. A few times it has stalled out completely.
I can park up and rev the nuts of it with no problems at all, equally off the line and using all of the rev range 1st, 2nd and 3rd it pulls away and is as nippy as ever. It only seems to be an issue while holding a steady speed at a normal rpm for that speed/gear. I thought it might be the coil and put in a new coil, plugs and leads but it's exactly as it was before.
