    Why ask this question?

    I suspect he is toying with the idea of making 40 horses out of his 35. Not going to happen, the 40 is a bigger bore engine–more cubic inches. Back to the carburetor question, carbs are engineered to supply the correct mixture at a particular CFPM rate. Sometimes swapping works out OK, sometimes it doesn’t.
