    while i'm in a posting frenzy....

    when i turn left, often the car really hesitates-i remember reading somewhere that a fuel tank design flaw draws the petrol away from the engine, or something-is this right, or did i imagine the whole thing? does anyone else have the same problem?

    With a low tank and a fast turn, I have experienced the same thing.

    Full-ish tank, no problem.

    Slower turn, no problem.

    This has been discussed here before. It is very common, if not universal. My car has had the issue from day one (when it was brand new). As I understand it (and feel free to correct me on the details), this has to do with the carburetor floats sticking due to g-forces. The carbs were designed for fore-aft placement. Under these conditions the g-forces act under braking, where any momentary loss of power is not noticeable or consequential. With the engine turned 90 degrees, these g-forces now come into play on left turns, causing momentary fuel starvation just when one needs to accelerate out of the corner. I don't think that it has anything to do with fuel pick-up in the tank and am consequently baffled (no pun intended) by Uro's statement that a full tank makes a difference. It never has in my car. It has always been matter of the g-forces generated.

    The problem was not fully put to rest until the engine was converted to fuel injection for use in the Lancia Stratos. Some Dino owners have retrofitted FI, bit this involves modifying the engine cover due to the added height.

    Only left ones!
    Or if you know its coming, as you feel the power go, pump the throttle twice, fast; there might be some juice for the pumps to pick up and get you going.

    Most of the time though, it's a Dino thing and you just drive around it. Amazing how the car handles loss of power half way though a corner!
