Iv done it the way brain has suggested ..and it works...I kinda had a hard time getting the lsn to turn smooth...so i removed it and installed a new oring..use a very light amount of grease(dont go carzy here),,and the lsn was so very easy to turn to find the sweet spot...

My friend has a 7port and gave up got a nova carb...

Once you has it set.leave it..and your done..
thanks brain
