Eddy 1405 tuning advice

Lash set at 0.018 intake and 0.022 ex.
Peeled carb off,reset float drop and level, drop was off a decent amount... :BangHead:
Confirmed all jets are stock, .095 rear and .100 main.
All else carb wise "looks" ok???
Pics of transfer slots from underneath.
Question, when I hear slots should be "squarish" is that when viewed from under or above??
(difficult) when installed.
Another question, while carb is off...I read/watched somewhere the the measurement of primary throttle blades to its bore SHOULD be approx 0.500" just as the 2ndary blades are starting to open. Is this correct? This one is approx 0.300". Linkage connecting the 2 shafts is what gets adjusted apparently?
Pics...drivers side is on left in pics.
Thanks
Steve
