    i was having that problem then discovered head gasket **** itself

    try dumping the coolant, letting the cyls dry right out, then starting

    as it warms up the head warps and seals the leak in the gasket. give it a go

    i'd start wtih the plugs - easiest and cheapest to check. If they are fouled then the problems will persist unless changed.

    Could be a couple of the carbs flooding - float needles passing. Just try turning off the fuel tap as soon as u stop next time, that should confirm it, if it starts normally again.

    Dont forget to turn the petrol back on.
