Very common problem with BF100

Very common problem with BF100's. You have a cracked exhaust pipe. The engine compartment is filling up with exhaust gases and robbing the engine of O2. Take a flashlight and look at the pipe underneath the bottom cylinder. I am sure you will see that it is cracked or corroded. Some people just drill a hole in the side of the cowling near the carb intake to let fresh air in.
