Why does my car think the air filter is a combustion chamber?

Dear Gavin,
I'm a bit confused. I can't visualise the pipe you refer to. Has the float chamber overflow somehow been connected to the air filter box filling it with overflow petrol
??????
Generally it sounds like your float chambers are flooding. How do you know your needle valves are 'doing the job'?
Try disconnecting this pipe (if it comes from the centre of the lid at 90 degrees to where the fuel pipe enters, and see if petrol is pouring out of the end? If it is change the needle valves.
Good luck

No, on my car (a recessed block 1300 MKIV) the fuel comes to the carbs from the pump round the front of the engine, alongside the air filters and to the carbs. The pipe on the air filter housing is metal, joined to the float chamber lids by about 2" of flexible hose.
I did a rudimentary check on the float chamber valve by blowing into the inlet while raising and lowering the float - when it's raised, I couldn't blow through it, but when it fell, I could.
I'm about to replace the rubber hoses, to stop the obvious leaking, and take it from there...
