lsn-ccw richens and cw leans
hsn-cw leans and ccw richens
idle-cw opens and ccw closes



Set air gap of throttle 1.5 mm,(idle screw), HSN Cw til it bottoms out then 3 1/2 turn CCW. LSN Flush with the throttle housing + 1 turn cw. Try to start, will be runnin really rich, if it starts. Turn down idle speed, then adjust HSN cw til you have good acceleration to idle. if your idle speed rises, turn it down. May have to do a couple times. Last adjustment LSN, turn cw slowly til idle speed starts to rise. when it rises you're running lean, turn it CCW till idle speed just drops. Blip the throttle you should be acceleration ok with some smoke coming from the muffler.Lean the HSN 1/8 turn CW till your satisfied.

here is a great tip to tell if your rich or lean it wont work if you have a air leak

Make ur engine run at idle then pinch fuel cable (engine will stall), but before it stalls it should rise rpm a bit. If it doesnt rise at all - u run too lean. If it raises hundreds of rpm - u run too rich. It took me 5 minutes (it is almost week that i have my first nitro) and my engine now works great. Then u adjust idle speed (gap on throttle). Set idle speed so that clutch doesnt engage. As for high rpm needle u have to try your car at high speed.
