But not related to the ignition problem Now You have said that you have an excellent spark and good fuel. the only other thing you need for start is the right airflow. or volumn. Dont know about your engine specifically but most everything else runs right around 14 to 1 on the ratio wise. Actually, jets are a different beast from piston engines. Between about 25:1 and 50:1 is normal, even for lightoff fuel flow. Stoichiometrically correct combustion is too hot. |
