Set your HSN at 5 Turns out, LSN at 2.5 Turns out. Idle you want about a .8 to 1mm gap when throttle closed. This should get you on the rich side, but you wont hurt the engine. Tune the HSN first going no more than at eighth of a turn at a time. Temps should be in the 200 to 250 range. Dont get hung up on temps, as long as isnt more than 280 you should be fine. Tune for performance & reliability. You are correct that it is to hot when it bogs down after a few mins. If you are still having problems after tuning this way, you need to check for an air leak.
