There are two tubes of different lengths for main and reserve in the tank. Sounds like your long one for main is blocked..

That's my 10p guess anyways

could be the vacuum diaphram in your fuel tap has worn out or has a pin hole in it which stops it working, think it's by passed when you use reserve!

You need to take the petrol tank off (turn the tap to off, remove the top breather hose, then hoses from the fuel tap), then remove the fuel tap - it's fastened to the underside of the tank with 2 bolts.

When you have it removed you'll see the 2 tubes.
