Fuel starvation

running a standard dellorto MB21 BS5 carburettor on a series 2 tv175. I have done a fuel flow check on the original fuel tap and it's showing with the fuel tap on-200ml per minute and with the reserve on-250ml per minute. The reason I'm asking is that I was cruising along at a constant 50-55 mph on a duel carriageway for about 6 miles and the scooter just cut out without warning. I pulled over and checked all the electrical connections,Cdi,battery,Earth etc and everything seemed fine.The Cdi,Stator and battery are brand new(50miles). I left it 10 minutes and after a bit of coaxing it started back up and was fine and got me home. Any advice would be appreciated.

Sounds like a soft seize

Yes thanks mate thanks. Flow of petrol with the tap on was to blame. I need to leave it on reserve as more petrol flows through the carb.
