Whats the ideal tuning starting point for the new GO carbs that have a little red go sticker on them? I'm in the process of breaking in a new GO 5 port (1/2 gal. so far) and it seems to favor a fatter setting on the LSN. If I try to lean out the LSN, I get a machine gunning sound after a 1/2 throttle run. Right now I have the LSN about flush and the HSN at about 1 turn in and it's still fat on top. I'm pretty sure I set the idle at 1mm.
