Hi Marcel, the revs rpm reading, I heard it could be an empty battery.

RPM Revs reading comes from dashboard wire that is colour  “Yellow/Black”  (usually)  and it works by signal from these devices  below (so check them)
– Stator
– CDI
– Harness (Mystery sensors inside hardness/ aka. Mystery diodes)
– Ignition Coils

Have a look at this topic below for some ideas on electrical troubleshooting and how to test parts with a meter

It is a GT250 yes but still carby, and they sometimes use same coils , caps,  & regulator as  GV125

No spark – GT250 Carby

Only stator / harness / switches and some other electrical parts are only for GV125 but either way it should give you some idea.
