I now have 14 flights on my elan with a P-80 se. The first flight of each day I get the blue propane flame at the tailpipe before the pump kicks in for the Kero. I have tried several ways to avoid this. I use just a short squirt of propane into the onboard tank, and I have cut the % of gas down to 60% from 80%. I still get the propane blue flame though.

It is becoming annoying as I give a quick burst of Co2 each time this happens.

The temps here in Tucson when I fly are in the 90's approaching 100 F. This morning it was in the 80's, and it still happened.

Has anyone else had this problem and if so how did you solve it?

Thanks,
Stan
