If I'm viewing the correct video. Look like running a bit rich, by the smoke its emitting. 1mm airgap is most a referance. you can go even smaller. Turn down the idle speed a bit or which you're confortable idle speed. Then slowly turn your LSN CW. If idle speed increases. it in the lean condition. Slowly turn the LSN CCW Speed will drop. Leave there. It take a few seconds change speed. You want it to be rich at idle. and turn lean @ off idle or lean after 1/3 throttle. Goin' WOT a second of blue smoke then clear of smoke. Adjust HSN first, It meters your fuel flow and consistant. Then idle speed. Last adjustment the LSN.

Remember, Nitro engine become lean at operating temp. Goes lean on half tank. In time you'll figure it out.

Good Luck!!! Have fun!!
