Sorry AVB, my bad I must have moved as I took it, coffee is not going to solve it

I will take another pic in the morning just for you. When I first got the carb a couple of weeks ago I put it on a motor and as I said the primer only squirted twice, I put a dribble of petrol into the carb and the motor started and ran fine. Yesterday I tried it on another motor in a different tank, primer didn't work and even with a dribble of petrol in the carb, not a murmer from it, not even a spit back. I fitted another carby and tank and the motor now runs fine
