Of course only do this after it has been properly warmed up. Then lean out the lsn an hour at a time until you get the proper throttle and idle response. Then work on the hsn until you don't get any lean bog and have plenty of good smoke. It'll take you 2-3 tanks or more to get it just right, but when you do you'll know it. The hsn is very sensitive on my go engines, alot more so than the lsn. 1/2 hour turn makes a huge difference between rich and lean settings.
