    Default 1.2 misfire

    I’m having big issues with misfire on my 1.6 8V on twin 40s.
    timing all good,carbs all good,fitted new coil/plugs/leads/roter and cap and still misfire.
    i have ordered an ignition control module that’s in the dizzy to try next.
    im starting to wonder if I have a bad earth? Where are the earth points because I can’t see one from the engine to body or gearbox to body.
    compression at 190 on all 4 cylinders so all good on that.
    purchased a second hand distributor but car wouldn’t even start with that on 🤦🏻*♂️.
    please help

    If you give it the beans/even to 7 grand it’s fine so I’m pretty sure it’s not a fuel issue
