If it passed the leak test ok, then check and do the following.
Make sure the carby slide is snapping back to bottom, a frayed or gummy cable will make the cable sluggish.
Check your float level, and then adjust the idle.
---------------------------------------------------------------------------------------------
Float level should 20 to 21.5mm on a stock carby.
you want to turn the carb and hold it on a slight angle to measure the float height, like shown here......
it should just barely be touching the inner needle, not depressing it,
here's the float height's of the most popular carbs run on our blasters.......Credit to Awk08
26mm vm mikuni - 20-21.5 mm (stock carb)
28mm vm mikuni - 22mm
30mm mikuni - 23-25mm
32/34/36 tm mikuni - 18mm
30mm oko - 19-20MM.
keihin carbs -
alot of these float heights came from this website, if your mikuni or keihin carb isn't listed above, it will be listed here.......

It is possible to check the fuel level by attaching a length of clear plastic tubing to the drain nipple , lifting it up the side of the carby, and cracking the drain screw.
The fuel should show in the pipe to the level of the carb body above the float bowl gasket.
--------------------------------------------------------------------------------------------------
Idle adjusting.
Set float level, make sure that all jets are clean and fuel flows freely from the float bowl drain when the screw is cracked open.
Start with air screw 1.5 turns out.
Set idle screw so that it has some sort of idle. With TORS it is the big screw under seat on top of unit. With no TORS is is the brass screw midway down carb body.
Warm up motor and then set idle screw for a faster idle, 2000rpm+
Adjust air screw either way to get the fastest idle.
Adjust air screw a little at a time leaving 10 secs or until the motor responds.
Re adjust idle screw for desired idle .
Make sure the carby slide is snapping back to bottom, a frayed or gummy cable will make the cable sluggish.
