<VV> smoke problem

[Rukshan Uddin]

hey everyone, i've been having some problems with my '65 monza

when i am driving above 50 mph (maybe even higher) i notice smoke coming
from the engine compartment
the smoke quickly stops when i slow down

im not really a car expert but from what i see
the smoke is coming from a hose that should attach to what i think is called
the vacuum choke control
when i reattach the hose, the car will start but stall if i am not
constantly feeding it gas

thank you
