180rx startup sputter
 

Started my 180rx in my new hawk tonight. Started fine. But, it did sputter a bit with flame visible between the tailbone and bell mouth/pipe.
Am I always going to have a little flame there on startup? With the exception of the idle auto tube I am not sure there is much I can change. Numbers look good in gsu. Once it got going the idle was fine, not hunting. So I don't know that autotune will help anyway.
I am going to paint a bit more heat shield around though...
I have 0.70-75" of clearance between tailcone and bell mouth as per jetcat diagram.
Thanks
Dave

Hi Dave.

Do you have your manual shut off valve closed when fuelling? Fuel can leak past the solenoids while fuelling and cause starting splutter.
I think its normal to get a bit of splutter. Especially on first start of the day.
My definition of splutter is short bursts of flame. Anything longer than a short burst is a fire :)

Hi
Yes fuel valve shut during fill. I also had just purged the fuel line...then had a short dry segment from the festo to the turbine (8"?).
I watched it flow gently in an start with appropriate rise in temps, similar to my 200 sx.
I will know more I guess after next start....I am running 2 cell LiMn but no trouble according to the gsu.

Thanks
Dave
