Fuel System: 140 Carb: - Running problem on 1971 144DL. Help.

Hi Guys,

I was wondering if any of you can help us with the latest problem on my new 144.

Ok, so here is the problem, the car starts and runs great. In fact very well. Until... the temperature gauge comes up to temperature then the fuel disappears and the engine struggles and then stops. But after a couple of minutes to cool off it starts again fine.

In the process of sorting this problem we have rebuilt the Carburettor including jets, needle and float valves, and we have also just replaced the fuel pump with a new one from Brookhouse Volvo.

The problem happens in the exact same place on our test circuit.

So, the only problems that we can think of are, fuel tank blockage (though why would that happen only when it heats up and in the same place?) or the fuel pipe is running to close to what looks like a non standard rear exhaust and it is getting too hot and causing a vapour lock.

Does any one have any ideas? Any help appreciated.
