Hello,

WOT - Wide open throttle problem when engine is warm

already checked
- fuel system (filter, fuel hoses, fuel pump and membrane)
- carburetor cleaned
- middle ignition plug is a little wet, after engine ran
- also checked rectifier (disconnected green cables) and thermostat (disconnected pink cable)

any ideas?


best regards from germany

The problem is solved. It was caused by a bad stator!
