my first thought would be that or if not an air leak on rubbers between carb mainfolds and engine manifolds or carb needs a rebuild

The 009 dizzy should be tossed in the bin and be replaced with a Bosch SVDA dizzy, the correct metal vacuum pipe and the vacuum hoses connected in the correct order.

Moby5153 and other people on here will know how those hoses should be connected on a 1600 single/twin port early bay.

I always worry about a professional tune up that doesn't cure anything.

Don't go buying or throwing anything away.

First take a look down the carb and see if the spray jet is spraying.
Then take the idle jet out from under the choke unit and see if it is blocked.
If you can, get a can of spray choke and carb cleaner and blast out the idle circuit.

Believe it or not, an 009 stands as much chance of being your problem as the recent earthquake in Peru. So... If you didn't feel the earth move.... Change your engine tuner before you change your 009. Someone has missed something very basic.
