Info required for old XR2

Can someone please clarify what the max rpm on a 200HP XR2 should be, read somewhere they are running faster than the 150HP XR2 I have but just wanted to confirm it.

Also, what should I be running the premix with this engine. After some discussions on this site, the 150 is being run with a 40:1 mix, should this be the same for the 200 version?


The less time I have to work, the more I get done !!!
