Thread: Carb advice please

Tweet

check the needle and seat on that side and look at that side setup on the float

There's a little gasket below the booster that if pinched or torn in the least, will leak. It will look like the fuel is coming from the primary venturi booster when in fact it is coming from below the booster where it meets the body of the carb (see #33 in the diagram below).

I replace the gaskets every time into an Edelbrock just to be on the safe side. They're fairly reasonable and then there's no question there.

If the previous owner had been "less than gentle" there could be other issues. As Pat mentioned, needles and seats are made of soft materials and if not treated correctly, they will mar and scratch. Fuel is under pressure in all of these circuits so it doesn't take much for a leak to develop.

Good Luck,
Glenn
