    Hi
    I'll try again and post this in the right place.
    Anyone have any ideas? My 68 T120 after about 1/2 hour sometimes cuts to 1 cylinder then will just cut out... It will restart after about 10 mins. There plenty of fuel any ideas anyone... Sticky valve? Timing? Air in fuel pipe? Not sure where to start.

    Might be plenty petrol but are carbs ok or full of sticky varnish (happens if engine not run for a long time, take float bowls off, if they are then jets probably struggling as well). Check points gap on both sets unless yer electronic ignition? Choke if fitted, isn't stuck on?

    Blocked vent in petrol cap? Whip it off quick next time it happens. If it restarts - problem solved. :) If it doesn't - I'm talking bollox again! :(:p
