slow running

fitted my new tap , cleaned the carb in a sonic cleaner, re fitted carb bike started after a few kicks revved nicely but wont tick over tried to adjust the ideal screw but it makes no difference, I have screwed it right in it stalls turn it out stalls, as yet I have not touched the mixture screw
got any ideas

sorted it a screw was missing on the throttle stop, just beem into the garage and noticed the bloody thing dripping petrol again

checked the pipes for splits, tightened all the connections in the end and a cup of tea it jumped out at me I had left the tap on free flow. now no leaks, the t80 lives again
I had forgotten how much I enjoy riding the t80
