I also usually clean it out before the pit guy sets it down after refueling.
Same with me it happened when I was using a fuel gun it would flame it ended up being to rich since we have changed that all good I can now use fuel gun or fuel bottle no more flame outs in pit stops
Try leaning it a bit and see how you go the picco likes to run pretty hot as well bud
