Default When The High Speed Needle is fully closed...DOES IT DO THIS? WEBRA 55

guys, in a Webra 55 engine 2 stroke which has been sitting idle for about 10 years now, i started it today, this is what going on with the carb:

a) the fuel is spitting out from the carb...visually its spitting/ sputtering out of the carb as though there is way too much fuel going in and i suspect that is the issue here...

b) the high speed needle seems to be doing nothing ...upon fully closing the needle also, the engine starts...i'm assuming the needle is completely not functioning ...idles very very strongly but upon opening the throttle, the engine dies....

my first question - when the high speed needle is fully closed, can any fuel still pass through the venturi? can an engine start with the needle fully closed? edit

second question- what could be the problem? is the needle faulty? if so how and why? i completely screwed out the needle and visually it seems fine.
