Wa-Hey!
Found the idle screw at last (don't laugh!)
Tightened all the way in - about 5 full turns - is that crazy?
Anyway, turned out to 1.5 at first, started first time - you legend! However, it was reving like a female dog, so I've turned it out further, now at about 3 turns and it still seems high revving but at least the rear wheel isn't flying around
Gonna go and have a ride around town now, see how it feels!
I LOVE this forum!

I found I was always resetting the screw until about 750 k then it seemed to settle down. Also I put some locktite thread glue on the screw, this seemed to stop it 'unadjusting' its self, but you can still adjust it if need be, its just a bit stiffer.

Just got back in, excellent!
Cheers for the advice, fella's.
Engine was certainly revving a lot more, so I guess that I'll just have to experiment a little.
My major concern now is that the additional revving is going to wear the engine too much during the running in period.
Any ideas what I need to be looking out for?
BTW - have another Karma.......................Oh go on

the revving shouldnt do any harm, just keep checking the idle speed

don't know if this will help, but when I first got my scooter it was doing the same thing. I got pretty pisted off, so once I got it started on the stand I let it idle high enough so the tranny engaged and the back wheel spun for about an hour and a half. After that no problems.
Also, did you put new oil in it. Make sure it is not over the max fill line. Hope this will help. Good luck!

So who do I check the idle speed, then?

Once the bike is really warmed up and the auto choke is off you should adjust it on the screw untill you get a nice steady purring, if you bike has a rev counter to about 1000 revs, if not you will have to guess it. Iff you set it too low it will sound as if it is struggling to keep going, , if its too high you back wheel will start to turn at around 1500-1750 revs WHEN THE SCOOT IS ON THE MAIN STAND. To drive you along the revs are at about 2000 for the clutch to bite if you have standard rollers as far as I can see, its difficult for me to tell as I dont have a rev counter, but it cant be too far out.

Cheers, Enu for your continuing advice, have another one on me.
Sounds as if my previous adjustments were made to soon, before the bike had warmed up enough so I'll make some changes later on today
Thanks again

It's not a car!! 1000 RPM is MUCH too slow, you will stall at the traffic lights, plus, a quick turn of the throttle will caue the engine to stutter and take far to long to get up to the clutch speed.
The clutch is set on all these chinese scoots (unless you have changed the springs) to start to bite at 1800 RPM
Idle speed should be just below that.
The Best way (with or without rev counter) is to put the bike on the stand, with it fully warmed up and increse the idle speed until the back wheel just starts to move, then back off a tiny bit.

"I've got a rev counter and I can't pull away at any less than 3500/4000 rpm" disregard my pulling away rpm forgot, I'm using 4.7g rollers/unlimited rev CDI
