Umm... this is a 1.5 litre single carb engine isn't it? So the Weber carburettor for this engine would be the 32 DIR twin choke progressive?
I had a 1978 single carb Ti engine with a Weber 32 DIR. This did not have a fuel banjo fitting, just a push-on fuel hose (jubilee clip obviously). However, there is a gauze filter immediately after the fuel inlet, which is accessible through a brass plug from underneath. Could this plug be loose, or have a damaged gasket?
Flooding of the float chamber is a possibility, but I would expect to see fuel weeping out all around the gasket line, not just around the fuel inlet. Has the brass inlet pipe fractured where it joins the alloy carb body?
Other exciting things to watch out for on the 32 DIR are the accelerator pump diaphagm splitting (happened to me) and the "sonic idle cutout" valve failing (this is the electrically powered solenoid plunger that stops the engine dieseling (running-on) when you switch the ignition off. I don't think either of those issues are relevant here though.
Good luck with your investigation, I hope you can pin down the cause soon!
