You are probably just loading up which means you need to lean it up a bit. Try turning the LSN clockwise 1/8 of an inch at a time, run the car up the street and back. Stop it and see how long it idles. Repeat this until you get a consistant idle. It should idle about 10-15 seconds before choking. Is that the LSN you have marked? That might be a MSN dont touch it until someone knows for sure.

ok you turn the idle screw to the right. but in very small increment's. try turning a little then run for a bit and see how it is. if you need to do it again untill it idle's ok. and yes he has the needles marked correctly. p.s. what temps are you running.

Do what fourwheels0 say. I had the same problem and I can fix in this way. You need to turn the idle screw on the side in
to get 2 mm idle opening always.
Please see in the forum more detail

Man that is not the LSN as in your diagram, its the Mid range needle... the LSN in in the little thing you attach the servo horn to. the one with the blue castanet jacket..
First take off the air filter and check the gap at closed. it should be 1mm then re set your midrange needle to flush.
Ok if you want to tune the LSN start the engine , let it warm up on the block ( wheels off the ground)
Then pinch the fuel tube right at the carb... what happens ? it may take up to 30 seconds to die ? maybe 10 or 15 ? What needs to happen is the engine should rev up slightly then die over a 3 to 4 second period. this is good bottom end tune... then check this by taking a few laps, stop the car , let it idle for 10 secs then take off fast... it should just rip off the mark.. if it dies thenm you need to lean the lsn 1/16th at a time till its right..
