I have a DLE 170cc engine and neither myself nor RC buddies cannot figure this out. So just looking for answers before I send it in for repair. The engine has been flying perfect for weeks and suddenly, one day it would not start. The problem is I cannot get it to pop while choke. I have change spark plug, carb, ignition fresh fuel and it just want pop or start with the choke off. Any idea what the problem can be would be great appreciated.



Thanks,
