Suzuki FA50 Oil Pump Test

Suzuki FA50 oil pump. Getting my FA50 back up and running after sitting for about 20 years, the engine seized up a few times. Decided to test the oil pump and found the little plunger on the tumbler was not plunging. It was seized itself. Thankfully I had another moped that I use mostly to harvest parts from, and borrowed its oil pump. This showed me what a working pump looked like and its plunger was fine, so I used its innards to swap into my broken pump. This is not an in-depth video on all things oil pump, just a quick test to show the insides and how to test it once put back together.
