Need advice on 78 CB750k8 carbs please!

Rockfozman
First time posting to this forum so hello everybody!  Now straight to business.  Trying to get everything to where it needs to be on my 78 cb750k8 carbs.  So far I have thoroughly cleaned them(the best that I know how) and replaced the gaskets, float needles and accel pump, everything else from prior ownership.  Adjusted floats but number one still leaking from overflow(hoping I bumped it while I was putting it together, fix that before anything). Stock #110 main jets, probably stock slow jet but not confirmed(never took slow jets out but could get air and cleaner through).  Mixture screws set at 2 turns out.  Carb boots are good.  It starts well and idles without choke but when I step on the gas too fast it pukes(too lean?).  FYI I did not have the airbox on while I was running it.  So, in short, how do I solve this?  Along with:

1. Plan on synching them with my homemade manometer when all else is done. (having a hard time finding hose fittings for the ports)

2. Looked inside holes for mixture screws.  #1 carb seems to be missing part of the gasket inside and dont see o rings without digging in there. (accidentally soaked them fyi).  #1 carb mixture setting screws in farther than the rest by probably 1/16", so I turned it extra to match the other carbs. Probably wrong I know.

3. Don't think it matters but while I'm at it should I get bigger main jets? (#110's, stock air, 4 to 4 exhaust) And when do the main jets start kicking in?

Any advice would be greatly appreciated. Thanks!!
