carb came in yesterday... it has a plastic cap over it... I can't unscrew it... should I just pull it out with some pliers??? and I was curious as to which direction to turn the screw to enrich or lean the mixture, and what would be the best procedure for testing this.

It Depends on WHAT TYPE of carb you have and where the screw is and then I can tell you which way to turn it to RICHEN or LEAN the mixture.(VERY SIMPLE BUT NEED TO KNOW THE TYPE OF CARB and WHERE THE SCREW IS) OR a picture of the carb.

Ok so its like the picture I put up but just a smaller version of it IT IS A CVK carb.
The Screw you turn COUNTER CLOCKWISE to RICHEN It and CLOCKWISE to LEAN it.
Once you start the Scoot and LET IT WARM up for at least 5 minutes to let the ENRICHER(CHOKE) close off the extra fuel for cold starts you can then Fine Tune the Fuel Ratio Mixture.
Here is how to adjust it:
Alleyoop
ADJUSTING YOUR FUEL RATIO SCREW:
FOLLOW THIS PROCEDURE, take your time DO NOT Be turning the SCREW fast and wait in between turns otherwise you will be off.
Warm Up the SCOOT for at least 5 minutes.
YOU WANT THE HIGHEST IDLE OUT OF THE FUEL RATIO SCREW YOU CAN GET.
ADJUST YOUR FUEL RATIO:
1. Turn the Fuel Ratio Screw Counter Clockwise 1/4 and wait 10-15 seconds to allow the engine to catch up with the new setting.
** IF ON THE FIRST TURN IT DOES NOTHING OR IDLE GOES DOWN- GO to 2.*** Otherwise GO to a. below.
a. If the IDLE GOES up repeat 1.
b. If the IDLE does not go up or it does nothing turn the Fuel Ratio Screw 1/8 Clockwise that should be the highest IDLE you can get out of the Fuel Ratio Screw-- GO to FINISH UP.
2. Turn the Screw Back 1/4 and GO to 3..
3. Turn the Fuel Ratio Screw Clockwise 1/4 and wait 10-15 seconds to allow the engine to catch up with the new setting.
** IF ON THE FIRST TURN IT DOES NOTHING YOUR PILOT JET AND OR PASSAGES ARE CLOGGED*** GO to CLEAN CARB*** Otherwise GO to a. below.
a. If the IDLE GOES up repeat 3.
b. If the IDLE does not go up or it does nothing turn the Fuel Ratio Screw 1/8 Counter Clockwise that should be the highest IDLE you can get out of the Fuel Ratio Screw-- GO to FINISH UP.
FINISH UP:
SET IDLE USING IDLE SPEED SCREW:
USING the IDLE SPEED SCREW set the Idle to 1500-1800 where it IDLES the smoothest AND the REAR WHEEL IS NOT Spinning-
TEST YOUR ADJUSTMENT:
Now while on the Center Stand GIVE THE THROTTLE a GOOD QUICK TWIST and Let go,
It should REV UP with with a nice VROOOOOOOOOM with no Bogging or Hesitation and Come back down to where you set your Idle.
DONE RIDE SAFE.
CLEAN CARB:
Take Carb Bowl off and clean Pilot Jet and Pilot Jet Passage and Main Jet and Passage.
Then come back and repeat this procedure.
