hello all, 1.4 cvh, carb engine, where does the hose go from here



im fairly sure it goes here, but the plastic pipe i found in the engine bay isnt long enough, so just want to double check!
im use to inj lol!



and while im at it, what is it actually for?

cheers for any help

 

vacuum diaphragm is the top 1 , it controls a flap to control how much warm exhaust manifold air or cold air enters the engine
heat sensor is the other , its , inside the airbox ,
at least 1 connects to the inlet manifold, behind the throttle
the other may connect to a 3 outlet sensor, also screwed into the inlet manifold
its all about the emissions bs , don`t know specific locations

 

First pic may be why it idles very low then. The other under the air box is connected. Id rather connect it up to see if it idles better before I adjust it on the cable.

 

i think only 1 of the under pipes had to be removed to take the filter box off
so i guess the heat sensor opens at a certain temp and opens the vacuum flap
so the vacuum flap pipe runs to the heat sensor
and the other heat sensor pipe goes on the alloy outlet take off behind the throttle
try nearest heat sensor oulet to alloy take off
