q-jet choke's are crap, just get a piece of wire and fix it wide open or remove the butterfly, try this first.

about timing, set your timing at 8 deg BTDC with the vaccum lines disconected and pluged at the carb, this will give you a good starting point, once done start the engine and check if the timing mark advances when you rev up the engine, should go to something like 20 degrees BTDC.

after this connect the hose to a ported vaccum source, the one with no vaccum at idle, this will give you a good average performance and no issues.

drive it and if still gives you problems replace the carb.
