TR4a Fuel from Carbs

["Mark Perry" <mperry425@hotmail.com>]

I was wondering if anyone would know why gasoline would be leaking from 
carburetor? This is a TR4a with dual carbs, and there is gas leaking out 
from one of them. I can see it dripping at the bottom of the air filter. 
I've tried adjusting the jet, but with no luck. Does this typically mean the 
carb needs to be taken off and internal adjustments required? Sorry, I know 
little about carbs.
