The Orie engine has no power.

My Orie engine is weak, please; The engine started normally in the morning. Wait for the platform speed for two minutes, and then slow down the throttle. Why does the engine speed slow down instead of fast? It takes three or four minutes to start normally. Excuse me, is there a problem? Don't put a spoon on your waist and say, you don't need a hot car. Just step on the gas in time and let the engine run at high speed for a while. Is it the throttle? Netizen yacht a said: Add a little throttle and it will turn off.
