Attention Kero Start Engines Users

If the engine fails to start, you can get excess kerosene in the engine. YOU CANNOT REMOVE EXCESS KEROSENE BY TILTING THE PLANE WITH THE NOSE UP IN THE AIR.

The kerosene will be captured by the exhaust guide vanes and will not run out of the engine. The nose must be tilted down towards the ground. The excess kerosene will then run out the intake. You may need a towel around the intake to absorb the kerosene. You may also need to clean off the starter o-ring afterwards since it may get kerosene on it.

Now why would the engine not start in the first place -

The kero start igniter failed. The automatic glow plug test may not detect a failed igniter! If you put your finger on it while the engine is starting and it feels cool, the igniter has failed. If your tried to start the engine with a failed igniter it will get some kerosene inside the engine. Do not immediately install a new igniter and try again without draining the engine.

The kero start feed line has not been primed. Please refer to the kero start instructions on how to prime the feed line. The fuel should be all the way up to the igniter. If you DID prime the feed line and it gets more than 3" of air after a flight, make sure the fitting is tight on the kero start fuel connection and the festo fitting is not leaking. Also make sure the solenoid is fully shutting off. If the fuel does not get to the kero igniter in a few seconds it may not start.

The fuel system has a high capillary resistance or the pump is a little weak and the kerosene will not get to the igniter. The pump will need to be adjust to a higher start voltage. This is adjusted by holding down the limits key on the GSU and then press the + key. A three item menu will appear. The first selection is for the number of cells in your battery pack. Use the + key alone to index to the next selection, UACCEL 1. This sets the minimum pump voltage to start moving fuel through your fuel system. To increase the voltage, press and hold the change value key and then each press of the + key will advance the UACCEL1 voltage by 0.025V. Try one or two increases at a time. To test the flow to the kero start igniter go to the test functions menu and select the kero start valve test. Press the change value key to flow fuel to the kero start igniter. MAKE SURE YOU DISCONNECT THE LINE TO THE KERO START IGNITER SO YOU DON'T GET FUEL IN THE ENGINE.....

If your igniter fails please call JetCat USA for a replacement. I personally fly with the kerosene start igniter and I am always amazed how smoothly and reliable it starts the JetCat engines. I "grew up" owning mid 90s kero start engines and I know what it is like to have rivers of jet fuel running out the tail pipe 9 out of every 10 start attempts. The JetCat system will not do this if operated correctly!!!!
