Hello everyone
2 days ago i was out on a ride with my 50cc chinese scoot (znen f11) and it just died and didnt want to start at all anymore. I pushed it home, changed the spark plug (no change) cleaned the carb and it barely started. But now it has an extremly tough time reving, twist the throttle and it stutters unless i twist the throttle very slowly which then doesnt rev past 4k rpm. I tried my other gy6s carb and it revs normal to what it did before but only to 6k rpm (still stuttering but it did the same before when i twist the throttle fast). Tried to work on it again today, put the old 25kmh block back in it and it revs to 7k rpm easily but dies down to 5k fairly fast and then revs up to 7k again in a infinite loop. If i hold the throttle to 5k rpm and twist it to max it acts like 2step and jumps from 5k rpm to 5.5k rpm.
I am suspecting the cdi box is faulty since ive read the symptoms of a faulty one online.
Any ideas on what it could be before i go spending money on a new cdi box?
