I'm 100% behind the: set the engine up without the Cline Reg' (or a Perry pump for that matter) first, approach.
Only then, went the engines running just fine, naked, hook up the gizmo and monitor the results.
The other way round can see you chasing any number of problems without knowing where they originate from.
I think you'll find it just fine with the remote needle but set it up to run absolutely perfectly, without the cline, first.
Good luck.
