Trying to repair for a friend. Sunny 150 cc gy6 type engine. Engine starts and idles just fine, however engine cuts out when reving above 2000rpm. Suspected usual, electric choke, however tested ok. Measured voltage at red/black wire form magneto coil and reads about 60 volts as at idle and increases slightly as you give it gas, however past about 2000 rpm, voltage drops to 0 then back to 60 repeats about every three seconds. Measures 63k ohms from black/red to blue/white wires coming from stator. I have not been able to find any similar problem posted. Please advise.
