Hey guys this is my first time owning a china engine and I’m really scratching my head on this one
The engine idle great but when I press gas it’s cutting sounds like a rev limiter but it sometimes goes higher I’ll link a YouTube video first comment
here is my setup
Atc200 with a running zongchen 250cc engine
New cdi
New coil
New carb pz27 main jet 120 pilot 38
*** UPDATE *** the engine was drowning I replaced my main jet with a 98 and now it’s working flawlessly
38 pilot
98-100 main is the way to go for an atc200 carb at sea level
