Default Problem with Collari XS12 not returning to idle

I have a problem that is beyond my limited tuning knowledge so any help would be appreciated.

Have a Collari XS12 that seems to run fine as long as the engine temp is below 230F but when it reaches this point it won't come back to idle. At WOT it runs at about 56MPH on a speed meter and then when you bring it back to idle it runs at about 30mph. Have taken the filter off to check and the carbie is definitely closed. If you just leave it at idle it keeps running at that speed. If you load it up with full brake then after a few seconds it drops back to idle. I thought it was an air leak in the carbie so to eliminate that I changed the carbie and sealed the base with high temp RTV. Still has the same problem though.

Any suggestions would be gratefully received am travelling to a big meeting this weekend and would prefer to race
