    Default Misfire (ready to put a hammer through the windscreen 🤬)

    My car has an annoying misfire,stutter,when driving say in 3rd going round a corner it stutters/splutters and does the same when cruising,iv fitted new plugs/leads/roter/dizzy cap.
    compression tested and all 4 cylinders at 190.
    carbs rebuilt by a well known man,rolling road pulled like a good one yet I still have this miss stutter.
    its a c16se on twin 40s.
    im fuming with it now,am I missing an earth?? Is the distributor goosed,any way I can test it???
    when you give it the beans it flys no missing or stuttering.

    Have you checked the timing with a strobe light? Mine did this and it was out so undone the clamp on the dizzy and adjusted it by turning it until I got it right been right since.

    Dizzy timing in Haynes is for leaded, it will need retarding a bit.

    Right, I’ve been Away a while, and I’m getting my nova mojo back up to speed..

    you are running a c16se, on carbs, With a lumpy cam on a z16se bottom end, but what dizzy? A vacuum advance or something like mega jolt might be the only way to get it Smooth.
    did you have the head skimmed?
    are you running super or regular petrol?
