912 ULS Starting and Fuel Flow Problems
in General Tech Discussion
13 years ago
I was encouraged by Rotax techs to install a backup electric fuel pump and a soft-start module to my engine, even though it started just fine on the first try every time. Added the pump. But now it does one of three things: With the electric pump running, and choke on, it will start right away, run fine for a few seconds, and then quit. Or, with or without pump running, but choke on, it will turn over once or twice and then kind of cough and stutter to a stop. (After either of thse it will usually start normally the second try.) Finally, with just the choke on and no pump it may turn over and then stop, or it may start up normally and run normally. Engine is cold and OAT in the 30's. After warming up it starts just fine. Any suggestions? I'm particularly concerned about it turning over a few times and then stopping, even though the key is still set to "Start".
