Any leaks in the system?

I'm not sure of the cause of the descrepancy. It could be water in the
pitot line or an error in the instrument. I am aware that most airplanes
have increasing IAS errors at lower speeds. My issue is that the IAS
points for my airplane seem to be quite a bit higher than in the skimpy
flight manual and higher than other people are getting. The Helio was
certified in the bronze age and only has minimal documentation. There
are no detailed charts for anything.
