Forgot to mention the Idle enricher is the only part that uses 12 volts on the standard carb.

thanks for answering,  i learned my scooter has no O2 sensor at all and what i meant with electronic carburator is that mine has a tps sensor, i got a much bigger problem last week my engine seemed to break down completly by making a horrible noise as if metal parts broke lose inside my engine itself.
i disasembled the engine from the scooter and remove the cylinder head and nothing seems to be broke except a leaking head gasket, can this cause a horrible sound? my engine sounded as if entire gears broke lose in half inside my engine but if u turn my engine by hand it does not make any sound. before this all happened i was testing how my engine performed with disconnected tps sensor cable, but i dont think this can cause the engine problems.

i ordered a new gasket set on Aliexpress, my scooter is 150cc Agility City it has TPS sensor and a 7/8 pin DC cdi. previous owner cut a wire .
