Well I was having a running problem last weekend that I posted earlier and was reading some posts and made sure my needle settings were flush on the HSN and 2.5 turns in from flush on the LSN for my 7-port and TA-DA!!!! RAN BEAUTIFUL THE WHOLE TIME!!! Was running between 245-260. I only barely tuned it with the LSN and turn it in a half turn more because it would load up a little at idle and it was perfect! Idled forever and tons of power. Thanks for the info guys! NO CARB PROBLEMS HERE.
