Nope, I stopped messing with this issue, what's more interesting, now during winter time when temperatures are around zero, even when car is not driving for several days, it ignites totally properly
.... last winter was opposite situation...quite strange situation. I will wait for spring and warmer days to see how it will do first ignition. If at warmer days it ignites improperly, then I believe there is some air suction in the system through some pipe/sealing due to expansion of material on higher temperatures. Rubber parts and plastics shrinks at lower temperatures, seems like everything seals fine now
