CB250 Fueling issue??

I will outline the symptoms.
1962 CB 250 twin carb

Bike will only run on one cylinder for about half a kilometre then cough sputter and run fantastic from then on. if you turn the motor off and restart it purrs like a kitten. If you leave the bike sit for a couple of hours the same thing will happen with it running on one cylinder for around half a kilometre.

Always the LH cylinder. Has new spark plugs and carbs have been cleaned with new o rings in the flange connections.

Any ideas are appreciated!
Nick
