That would be most of a ml there in the fuel line, but I don't count it because I can't keep the engine running much past the fuel line showing air for 1/3 it's length, half at best.

I noticed the same. it could be easily fixed with a much thinner fuel line like the old electric blue 1st version had. I may experiment with a thinner tube that just fits insìde the fat tube we have now.
