1.6 is a crossflow

If it has a carb(s) suspect they need a rebuild. They fact it only runs with the choke on would seem to indicate a lack of fuel. If injectors, might want to run a concentrated mixture of fuel/injector cleaner thru the engine, make a temp connection from a portable fuel can to the fuel pump.
