also your condenser is to large for this compressor , your condensing unit was projected for another load with an large evaporator , using it in low back pressure application like OC with small surface area evaporator , that condenser is way to large ...and you will heavly deep enter in the superheat issue.
using cappilary tube as XV ...is usless using an sight glas , because you will have both liquid/gas at enter of cap tube anyway ....sight glas / reciever is mandatory when you refill a unit that actually use an TXV as expansion valve.
also using a copper reciever as accumulator in suction sided , will not work as a right "accumulator" .. you will have anyway liquid refrigerant flood back intro the compressor and oil issue.
