Being new to 2T, you may not know that deleting the pump and premixing that you really should rejet. You are displacing some of the fuel that went through the carb with oil, so you are running a little lean. Go up one or two jet sizes on the main. As well,(and I haven't looked into it) some oil pumps had split lines with one that branched off to feed the bearings at the end of the crank. If yours only had one line to the carb/intake area, go on with premixing. If there was a feed for the crank bearings, the oil injection needs to be working as intended. There is a wealth of info out there. Google Graham Bell "Two Stroke Tuning". The Jenning Two Stroke book will come up on the same search.
On your original question, there is no real advantage with MMO in a 2T that is premixed. In an oil injected system, there is a small, insignificant, benefit of MMO keeping the carb slide wet and lubricated with todays dry fuels.
