I didn't even think about the housing volume gain. Makes sense why it is doing what it's doing.You are not well enough informed on this subject and therefore just don't get what is being said here, Neither the carb nor the engine suck in air/fuel, atmospheric pressure rushes in through the carb body when the port or reeds open due to the case pressure being lower than that of the atmospheric pressure outside of it, the outside air is not drawn away from the carb in a vortex or vacuum or ever air speed around it because it's NOT moving fast enough nor does it have the pressure to over come the atmospheric pressure so the only fight here is you beating a dead horse not understanding the facts! Your gains though small are very easily explained since you've unshrouded the carb of it stock cover the volume was slightly increased which is normal and to be expected, put a more restricted air filter on and you'll lose that volume gain it's really quite simple!
@DAMIEN1307 I have a similar filter.
