Need Quick Fuel carb tuning assistance

Dropped fuel level to bottom of sight glass (has the large sight glasses). Cleaned up idle AFR just a touch 13.5ish, engine also idled up just a hair with this adjustment. I went down to 68 jets and it does not like it. Lots of surging, going back to #70 (stock jet) and go from there. Bought 8' of hose today, so I can hook up the vacuum gauge and check cruise vacuum.
I think dropping jets size and fuel level at the same time may have caused this bad surge. <---- Need opinion on this.
Also went from #76 to #78 jets in the rear to fatten up the WOT. Last test with the #76 ( stock jet) AFR went to 13:1 at 5000 rpm. If this change helped WOT, I will adjust with the PVCR from here on out.

Am I doing this correctly or am I running off in the wrong direction.
