i think the electronic,s under the seat just crank,s up the tick-over when the alternator is under load.
has your,s got the semi-automatic choke ? (black plastic dome)
check air filter is reasonably clean. check rotary arm / distributor cap / ignition leads.
there should be a little window on the front? of the carb. Check the level is half way.

did you remove the choke flap as well ?
iirc, the box under the seat controls one of the 2 solenoids on the carb

as long as it,s not pulling shut when your driving, it should be ok eh.
you might have to disconnect or "wire in" the idle control solenoid then, to lower the tickover if the screw is fully out
