AAN Stand gas charging pressure?

How much charge pressure do you have on your AAN engine? There seems to be a problem with me, but unfortunately I don’t know what…, I have in the stand gas 0.2 to 0.4. Say I just stop like this and have 0.4… 5 meters further and then I have 0.2 and so on. Also when running from the gas and letting it roll it constantly! 0.2… What can that be? P.S. If I take off the oil cover while it is running… the engine almost didn’t fluctuate at all…. MfG
