EFI no choke. I would say it is normal, as long as it doesn't keep that high idle for to long, when you say high idle, ? do you mean a bit higher than normal or does it really idle high. And do you open the throttle a bit when starting it?

There will be others here that may have a better answer than me though....

 

Sounds familiar,  I don't think it is anything to be concerned about.
