Yes AVB,
That is a pretty rubbish setup and yes I fitted another filter base and the old one went straight in the bin. What threw me here was I thought the primer was anot working but I couldn't get a peep out of the motor with a squirt of starter fluid down the throat of the carby. I ended up putting a squirt into the manifold with the carby off and it fired so that proved it was a carby issue
