The above photo is of my Edelbrock 1404 carb in my V8 Marcos and have a fuel leakage problem.

After 3-4 years on the road following a full resto i have had my first issue so overall not too bad and take some comfort that the carb was not my installation.

Last week after a brief stop to refuel the Marcos it would not start and put it down to the usual hot start issues or a batch of dodgy fuel, after leaving the car for 30 mins it started again only to cut out again whilst slowing down for a island and again had to leave the car. Drained fuel and put fresh in, looked at plugs and were all black, cleaned them up, (whoever put those chassis rails right next to the heads needs a kick up the backside but leave that for another day)

Just started Marcos again, sweet running, stopped it after two minutes and tried to start again and would not start, head under the bonnet and i could see fuel pouring out from the carb onto the manifold, took the airfilter off to see the carbs full of fuel but was not coming from the two jets but filling up from in the area of the two red arrows on the above photograph. So basically the carb is still filling up after engine stopping and i can hear the knock knock of the fuel pump every few seconds with the ignition switched on hence the engine flooding with fuel and not starting until i have left the car which presumably allows time for the fuel to dry off. Engine is the V8 and Edelbrock 1404 carb, the Marcos was set up on a rolling road 6 month ago and was running great until last week.

Any advice gratefully recieved,

I would say the needle in the float chamber is stuck or has some muck in it or your float has punctured.

The two things that you are pointing at are the primary boosters, they are fed fuel by the primary jets and they are the normal place for fuel to enter the air stream. Like what has already been posted it will either by muck in the float valves or a float with a hole in it.

Thanks for the replies, i shall take the top off and get to the floats to inspect further,

Yes, one float with a hole in it taking on fuel.

Got a new set on order,

Thanks again for advice,
