Dripping fuel

Advice please. I have fuel dripping from the main jet plug of empi34p-3 how do I solve this? Thanks in advance

I’m not sure what you mean with the main jet plug,
When your looking at the engine/carb -is it leaking on the left side or the right side ?
It may be the spindle bush which is left and right near the bottom ?
Rebuild kits are available for a lot of different carbs or repro carbs can be purchased

It’s on the left, when looking at a diagram of all parts for the carb it’s called the main jet plug. Have been advised to change the O ring, it could be perished. Going to give that a go today. Thanks

Ok changed the O ring 3 times but kept splitting so put in a brass washer for a hydrolic brake, no more leaks yeeeeeeh
