Hurricane Rotol mixture controls?

[Dano]

Ok, so I feel the need to try and get this straight in my head lol...

Are the mixture controls on the Hurricane Rotol are reversed? When in the Rich position it shows as 0% and when Weak at 100% or is that supposed to mean the amount of air in the mix, ie; 0% air at rich and subsequently lots of air at weak mixture? Colour me confused!!!

The controls are obviously designed that at idle you can only have a rich mixture and can only go full weak once past 50% throttle, so assuming it's not reversed at higher throttle settings more air is in the mix yes?

Also, there appears to be a bug in that as you reduce throttle below 50% you can physically see the mixture control be collected and move toward the rich end along with the throttle, this does not appear to affect the actual mixture settings until you touch whatever control you have set it to however? So you can have throttle at idle and mixture at full lean which should not be possible due to the physical controls right?

Anybody care to educate me?

Thanks.
