    Hey Guys,

    I'm finishing up the restoration on my Fiat Dino spider 2.0 and I'm trying to find out the correct jetting setup on the carbs. Everything I can find gives me the specs on the 2.4 engine but I can not find anything for the 2L. I would think with the smaller displacement there would be a difference. Anyone know??

    Thanks in advance.

    Bear in mind that the original jet sizes published 40 years ago will act as a starting point but will be wrong for the fuels available today. For optimum performance the jets will need to be adjusted which can only be done properly with on car tuning.

    those are the late type Fiat Dino carbs
    you can use the same spec as you found on Fiat Dino 2400
    the early carbs have different jetting
