Got the scooter now for about 2 weeks and put about 110 miles on it...everything is great but when new and out of the crate, the idle was running at around 1900 - 2000 r.p.m.s Didn't run it for a day or so and it seems like it's idling around 1400 r.p.m. and sometimes will stall at a stop. I only ran it for 10 minutes this morning. Is it just a matter of taking off the seat and adjusting the idle screw on the carburator to bring it back to 2000 r.p.m.? Or is there more to it?

I think that would be your best bet, because those are sealed carb and really cant do more with those carb but that. I would say your fine but everyone else usually buys a aftermarket carb and up jets, they are a little lean from factory

If your mixture screw is sealed, you can carefully drill out the plug on the side of the carb where the mixture screw is to adjust it. Just drill a little hole in it slightly off center and then screw a sheet metal screw in there a little but and then pull on that with some pliers and it should come out. If not drill another hole or two in it and pry it out with a nail or whatever. The screw controls the idle fuel/air ratio. Here's a guide for adjusting that screw: www.scooterforumonline.com/index.php/topic,1603.0.html

If I was to drive the bike in South Florida, where the weather is always warm, would a lean setting of the carb be better for me, than for someone who eg lives in Northern Canada with cold weather?
Also, I live very close to ocean level.
How does the elevation level, and temperature interact with a lean carburetor setting?

I have the same on my tao. It goes down once the engine has reached a higher temp. Sometimes you need to just twist the throttle a bit, b'cos the idle mode might hang at 2k rpm. Once you twist and let go of the throttle, the rpms go down.

I adjusted the carb this morning after a spin. Put it up on it's stand, and went at the idle screw...turned it up a bit and set it at 1900 r.p.m. and it was fine, then every minute of two it would just, on it's own, go up to 4000 r.p.m. then back down, and it did this repeatedly with back wheel spinning. So, I tinkered with it and I think I got it just right as it was not stalling on me, but response time at stop signs is a little hesitant. By the way, I got a 2012 TaoTao and the carb is no longer sealed. There are two screws on top of the bowl which will make it easier to clean when I do that.

It's actually better to lower the idle RPMs. I know when you give a spurt of throttle, it stalls and dies. However, even at 1400rpm, it still runs pretty rich. If you're running WOT for a while, and the engine has heated up, at a red light, it runs pretty high on idle (close to 2k RPM).
When summer comes, it may be better to lower the idle.

Ok.. why is it important to adjust the idle, what exactly is 'idle' and how do you monitor/measure the idle? Just curious, a newbie here so I have no clue about this. Thanks..

But how do you monitor it, measure it and adjust it?

Thanks for the link! But how do you measure RPM's? You people seem to spout it off so effortlessly. Is there some kind of device I can buy to properly measure the RPM's?

Take a look at your speedometer...you'll see reading marks for Kilometers per hour and miles per hour. Start your scooter, and let it idle...look at the reading on the speedometer ... should be somewhere between 1400 and 2000 which is your rpm reading (rounds per minute, as in a tachometer). You already have it, just gotta learn to read it. For instance, if you're stalling at lights, you may need to adjust the r.p.m. with a philips screwdriver and turn it up a bit. I keep mine at around 1900, but I'm told it could be lower, so I'm going to toy with that. One screw in the seat compartment gives you access to the adjustment screw. Turn to the right and your r.p.m. will rise a bit. Just be careful and have the scooter on it's stand. If your back wheel starts spinning, you've gone too far...back it off. Ain't this fun
